For some very strange reason I cannot explain, everytime I'm with someone of color, white people inexplicably die suddenly, all around. Only in the Twilight Zone. Ridiculous white genocide conspiracy theory for panic. Irrational panic is promoted as a justification to keep promoting a constant flow of hate speech, hoping to normalize racism, the conflicts, crimes and unfair inequality that come with it...
What may be true and already was, fantasies of "pure breed" come with tropes of "uncleanliness", superiority and inferiority, society stratification, identity politics, etc. Actual science demonstrated that the health of a population is improved by diversity and mixing and that extreme bottlenecks and inbreeding promote aberrations. In cosmopolite societies, the illusion that color affects anything other than color fades. The white supremacist ideology is challenged. Not the people.
