*shrugs* Whilst a lot of people seem to get it, there will always be those extreme people on the fringe who want to wipe them out in their minds. Maybe erasing painful memories of whatever racism they've experienced, in their mind or otherwise, by seeing all white people as inferior. Because it's not like they didn't conquer most of the world, build most modern technology, etc. On the other hand, I have nothing against people of any race. People of every race can be dicks, and if there were only black people left, their so-called superiority would have been "watered down" by every other race they bred with.
Besides, anybody halfway smart knows the best way to survive is to have as many different types people as possible.
But then racial unity doesn't give people a power trip for their wank fantasies, does it?
