See, you may be playing at Hitlerian philosophy; mine's more Nietzschean. The strong prevail, the weak die out. If white people die out? Fine, means they were too weak to be worthy of preservation.
You should go scream in German about it. Don't forget to whomp on a podium while you're at it. And I'm not shilling for anyone. I'm saying that if somebody is dumb enough to let themselves get played, they deserve what happens.
