Biological extinction is the permanent loss of a species. The process usually involves habitat destruction, predation, or climate change—gradual mechanisms that eliminate reproductive capacity. Extinct species don't reappear; extinction is definitional finality. Humans have caused dozens of species extinctions; several more face imminent extinction. The word carries ecological weight.

Yet extinction differs from other forms of conflict. A fight involves two combatants competing; extinction is one-way elimination. The distinction matters: a fight implies potential victory for either party. An extinction presumes one party's unilateral dominance. The terminology shifts from conflict to elimination.

The Norris fact reframes engagement: he doesn't fight because fighting implies mutual risk. Instead, he generates extinctions—one-way processes where the outcome is predetermined by structural mismatch. The meme suggests that asymmetrical power becomes a category error: it's no longer combat but elimination. It's one of the darker facts because it acknowledges that some matches aren't fights at all.
