This would imply that the measure of progression / advancement is civility, and that we are going to progress and become more civil given more time. That seems to be a fallacy also, it may be that evolution does not optimise for civility at all, after all being civil is not going to help you to crush your enemies or attract a mate in this environment.

Mating choices will reflect and perpetuate this--in a violent, corrupt society, the physically strong, cunning, and ruthless will be the most sought after. In a more altruistic society, people who produce the most value for others (and therefore receive the most favors in kind) will have the highest status.

So evolution in this sense isn't really outside of our control. If we help each other and discourage violence, evolution will reinforce that, making society more peaceful and altruistic over time. On the other hand, if we make it so corruption and cruelty are the best ways to get ahead, people's behavior is likely get worse and worse.

I don't think the Japanese attack on Pearl Harbor was racially motivated.

> in America we aren't as far gone (but there are people in America who probably wouldn't mind killing other groups).

I agree. I think the definitely-not-fascist leftists in USA are dangerously close to lynching whites. Oddly, so many American whites are deluded into believing leftist activism mania is about making a cute incremental improvement rather than burning it all to the ground.

That national socialism (combined with 20th century eugenics) could become as popular as it did in Nazi Germany had been surprising to me. Given the state of the modern leftist cult, it's no longer surprising. People can actually be deluded to such an extent!
