The systemic white genocide isn't really a thing. Sure, there is political violence against whites in Africa, but South Africa ain't anywhere near the worst offender there, and the rate of violence there is comparable to the rate of political violence against LGBT in the US, so if you're going to call the political violence in South Africa white genocide, you shouldn't object to calling Musk genocidal for his transphobic views.

More to the point, though, even talking about it as a genocide is really about cheapening the definition of genocide and denying the existence of problems that don't affect one or the community one lives in by drawing false equivalencies.
