Cohesion begins with language. Long before societies fracture, before militias mobilise or neighbours turn on neighbours, something quieter takes root. It begins in conversation, in pamphlets, in sermons, in broadcasts. It begins with the gradual repositioning of a fellow citizen into something alien, suspect, less than fully human.

Hate speech is rarely spontaneous; it is cultivated. It reduces economic anxiety to ethnic blame and transforms political frustration into moral accusation.

History offers few clearer illustrations than the formation of Adolf Hitler in early twentieth-century Vienna. Vienna was not merely a backdrop but a laboratory of populist resentment. Rapid urbanisation, economic strain, and imperial decline created a market for scapegoats. The city’s mayor, Karl Lueger, demonstrated that antisemitism could be electorally profitable, refining a politics that fused grievance with spectacle and portrayed Jews as corrosive outsiders.

Hitler absorbed both ideology and technique. He learned the potency of repetition, the choreography of mass rallies, the persuasive force of humiliation reframed as patriotism. By the time he articulated his worldview in Mein Kampf, hatred had been systematised into a theory of racial struggle. The Jew was no longer a neighbour but a pathogen within the body politic. When extermination culminated in the The Holocaust, the violence did not materialise from a vacuum. It followed years of rhetorical conditioning that normalised exclusion and sanctified cruelty.

For Rwanda, these lessons are not distant abstractions. In the years preceding the 1994 Genocide against the Tutsi, dehumanising rhetoric saturated political discourse. The Tutsi were repeatedly described as "inyenzi”- cockroaches - an image crafted to erase personhood and dull empathy. The hate broadcaster Radio Télévision Libre des Mille Collines fused propaganda with immediacy, naming individuals and directing militias in real time. Language did not merely accompany violence; it choreographed it.

When approximately one million people were murdered in roughly 100 days, the speed stunned observers. It should not have. The groundwork had been laid meticulously. The killers had been conditioned to believe they were performing civic duty. The machete followed the metaphor.

What renders hate speech especially dangerous is its afterlife. Even after mass violence subsides, narratives of suspicion persist. In parts of the Great Lakes region today, minority communities such as the Banyamulenge in eastern DR Congo are still framed through tropes of foreignness and illegitimacy. Digital platforms now accelerate these narratives across borders with unprecedented speed. The vocabulary shifts; the logic remains.

Within Rwanda, post-genocide reconstruction has centred on unity, reconciliation, and legal prohibitions against divisionism. The objective has not been to extinguish debate but to prevent the reintroduction of dehumanising frames that history has proven lethal. Observers may debate calibration, yet the premise is difficult to dismiss: when speech becomes a staging ground for extermination, regulation becomes a matter of collective security.

It is in this context that Rwanda’s engagement in multilateral anti-racism forums, including the follow-up processes to the Durban Review Conference in Geneva, takes on particular significance. In a digitised environment, incendiary narratives traverse borders effortlessly, while fragmented national laws leave enforcement porous. Impunity rewards those who radicalise discourse for political gain. At what is often referred to as Durban +25, Rwanda has advanced proposals calling for stronger regional coordination against hate speech impunity. The logic is neither parochial nor symbolic.

The most difficult work, however, is not legislative. It is pedagogical and cultural. Many of the divisions that surface in moments of crisis are inherited, absorbed through textbooks, folklore, partisan storytelling. To confront hate speech effectively requires more than penal codes; it demands a deliberate unteaching of mythologies that rank human worth.

In addition, in this multipolar century, regional stability will outweigh imperial aspiration. For Africa to translate demographic dynamism into durable prosperity, it must address its fractures internally. Ratifying stronger regional commitments against hate speech would not erase history; it would signal that its lessons have been absorbed.

Violence rarely announces itself with a drumroll. More often, it whispers first. The responsibility of this generation is to recognise the whisper for what it is and to answer it before it swells into something irretrievable.
