Freedom of speech is widely regarded as the cornerstone of democratic societies. It allows individuals to express ideas, challenge authority, and engage in open debate without fear of retribution. Yet this same principle, when exploited by ideological extremists on both ends of the political spectrum, can become a powerful weapon in the service of totalitarianism. The far-right and far-left, though ostensibly opposed, often employ strikingly similar tactics: they invoke the banner of free expression to spread divisive rhetoric, silence opposition, and erode the pluralistic foundations of liberal democracy. In doing so, they transform a liberating right into an instrument of control. At its core, freedom of speech is neutral. It protects both the profound and the profane, the truthful and the false. Democratic societies accept this trade-off because the alternative—state or social control over acceptable opinion—is far worse. Extremists, however, do not accept this neutrality. They view open discourse not as an end in itself but as a battlefield on which to conquer. Both the far-right and far-left begin by positioning themselves as defenders of free speech against a supposedly oppressive establishment. The far-right claims that "political correctness" and "woke" culture silence traditional values and national identity. The far-left asserts that "hate speech" and systemic privilege drown out marginalized voices. In both cases, the grievance is framed as an existential threat to expression itself. This narrative serves a crucial purpose: it grants moral permission to push boundaries, escalate rhetoric, and normalize ideas that would otherwise be marginal. Once these boundaries are pushed, the second phase begins. Having used free speech to gain visibility and influence, extremists then seek to restrict it for others. The far-right may demand the banning of "anti-national" or "globalist" perspectives. The far-left may insist on the removal of "harmful" or "oppressive" viewpoints. In both instances, the principle of free speech is invoked selectively—celebrated when it serves the cause, condemned when it challenges it. This selective application is the essence of weaponization. History offers clear warnings. Totalitarian movements rarely seize power by immediately abolishing free speech. Instead, they exploit it during their rise, only to dismantle it once secure. The Nazi Party in Weimar Germany provides a stark example from the right. In the 1920s and early 1930s, Adolf Hitler and his followers relentlessly demanded unrestricted speech, portraying restrictions on their rallies and publications as proof of Jewish-Bolshevik conspiracy against German freedom. Street speeches, inflammatory newspapers, and public demonstrations were all justified as exercises in free expression. Once in power, however, the regime swiftly abolished all opposing voices, burning books, banning parties, and establishing total control over media. From the left, Bolshevik tactics in early Soviet Russia followed a parallel path. Lenin and his allies used underground newspapers, public agitation, and parliamentary platforms to spread revolutionary ideas while decrying Tsarist censorship. Freedom of speech was a central demand of the February 1917 revolution. Yet within months of the October seizure of power, the Bolsheviks closed opposition newspapers, dispersed the Constituent Assembly, and established the Cheka to suppress "counter-revolutionary" speech. By the 1920s, only the Party line remained. These historical cases reveal a pattern: extremists exploit the openness of liberal systems to propagate intolerance, then dismantle those systems once they achieve dominance. Contemporary far-right and far-left movements, while operating in more constrained environments, follow the same playbook on a smaller scale. Modern far-right movements—ranging from white nationalists to populist authoritarians—present themselves as the last defenders of unfiltered truth against elite censorship. They argue that mainstream media, academia, and technology companies conspire to suppress inconvenient facts about immigration, crime, culture, or history. This narrative allows them to justify extreme rhetoric. Conspiracy theories about demographic replacement, globalist cabals, or cultural decay are framed not as bigotry but as forbidden knowledge that must be spoken aloud. Online platforms, talk radio, and alternative media become vehicles for this message. The more provocative the content, the better: outrage generates attention, and attention builds movements. Crucially, far-right actors often demand absolute freedom for themselves while working to silence critics. They may harass journalists, academics, or activists who challenge their views, using coordinated online campaigns to intimidate or dox opponents. Public figures who speak against far-right ideas are labeled traitors or enemies of the people. In some cases, this escalates to calls for legal restrictions on "anti-national" speech or the deportation of dissenting voices. The end goal is a society where only one narrative—centered on ethnic, cultural, or national purity—is tolerated. Free speech, having been used as a battering ram to gain influence, is then redefined as the right to express "traditional" values without contradiction. Any deviation becomes treasonous. This is totalitarianism in embryonic form: a society where dissent is not merely wrong but existentially threatening. Far-left employs a mirror-image approach. Progressive extremists frame their demands in the language of harm reduction and justice. They argue that certain forms of speech—whether misgendering, cultural appropriation, or questioning affirmative action—cause tangible harm to vulnerable groups. Therefore, such speech must be restricted, not for the sake of power, but for safety and equity. This framing allows far-left activists to use free speech aggressively while simultaneously advocating its limitation. Campus protests, social media campaigns, and public shaming are all justified as necessary countermeasures against oppression. The goal is to "punch up," not to silence debate, but to ensure that historically marginalized voices dominate the conversation. Yet the practical outcome often resembles censorship. Speakers with controversial views are disinvited or shouted down. Professors face professional consequences for deviating from approved orthodoxy. Online mobs demand the firing or deplatforming of individuals who express forbidden opinions. Institutions—universities, corporations, media outlets—are pressured to adopt speech codes, bias response teams, or content moderation policies that align with progressive ideals. Over time, the definition of "harmful" speech expands. Initially limited to overt bigotry, it comes to encompass any critique of identity politics, affirmative action, or gender ideology. Questioning the premises of the movement itself becomes evidence of malice. The result is an environment where self-censorship becomes rational: better to remain silent than risk social or professional ruin. Like their far-right counterparts, far-left extremists ultimately seek a society where only one moral framework is permissible. Free speech is celebrated when it advances equity and inclusion, but condemned when it challenges them. Dissent is not engaged but pathologized—labeled as phobic, privileged, or violent. This, too, is a step toward totalitarianism: a world where ideological conformity is enforced through social pressure and institutional power. Despite their opposing ideologies, far-right and far-left extremists employ remarkably similar methods: 1. Victimhood narratives: Both claim to be silenced by a powerful establishment, justifying escalation. 2. Moral absolutism: Both view their cause as existentially vital, rendering compromise or pluralism immoral. 3. Dehumanization of opponents: Far-right rhetoric portrays critics as traitors or subhuman; far-left rhetoric frames them as oppressors or irredeemably privileged. 4. Control of institutions: Both seek to capture universities, media, corporations, or government agencies to enforce their vision. 5. Selective free speech: Both demand unrestricted expression for themselves while working to restrict it for others. The convergence is most visible in their shared intolerance of liberal neutrality. Classical liberals defend free speech even for views they despise, trusting that truth emerges from open debate. Extremists reject this. They believe truth is already known—their truth—and that allowing error to circulate is dangerous. This shared rejection of pluralism creates a pincer movement against liberal democracy. From one side, the far-right demands loyalty to nation, tradition, or race. From the other, the far-left demands allegiance to equity, identity, or historical reckoning. In both cases, the individual’s right to think independently is subordinated to collective ideology. The process is gradual but relentless. It begins with the normalization of extreme rhetoric under the guise of free speech. Inflammatory ideas gain traction because platforms—committed to openness—allow them. Audiences radicalize. Movements grow. As influence increases, pressure mounts to restrict opposing views. Far-right actors may push for laws against "anti-patriotic" education or immigration advocacy. Far-left actors may advocate for hate speech legislation that disproportionately targets conservative views. Technology companies, fearing backlash from both sides, adopt inconsistent moderation policies that alienate everyone while satisfying no one. Eventually, the center collapses. Moderate voices are drowned out by polarized extremes. Trust in institutions erodes. Politics becomes existential. In such an environment, authoritarian solutions become appealing: a strong leader to restore order, or a revolutionary vanguard to achieve justice. History shows that totalitarianism rarely announces itself. It emerges when the safeguards of liberal democracy—above all, genuine commitment to free speech for all—are hollowed out from within. Extremists on both sides contribute to this hollowing. The antidote is not to abandon free speech but to defend it consistently. This means tolerating discomfort, engaging bad ideas rather than suppressing them, and rejecting the extremist premise that speech itself can be violent or treasonous. Democratic societies must resist the temptation to adopt extremist tactics in response. Banning far-right symbols may feel satisfying but establishes precedents that far-left movements can later exploit. Similarly, expansive hate speech laws designed to curb progressive excesses risk being turned against minority viewpoints. The harder but necessary path is cultural: rebuilding a shared commitment to pluralism, debate, and individual conscience. This requires courage from institutions, leaders, and citizens alike—courage to allow offensive speech, to answer it with better speech, and to reject the siren song of ideological purity.
