It seems to me that in my lifetime I've met plenty of whites who are brimming over with hostility and resentment, and full of schadenfreude, while at the same time making an effort to appear the opposite. They actively root for -- and sometimes facilitate -- others' downfalls, while simultaneously wanting a reputation for being good people.
You've undoubtedly met people like this, the type who seem to always be able to find a reason to hate somebody. They'll even hate people they barely know, simply because they're jealous of them for some reason.
One racial difference I've noticed is that you simply don't meet black people like this. I'm not saying black sociopaths don't exist. There are black serial killers, and people like Jesse Jackson and Al Sharpton in public life. But I honestly can't think of a single black I've ever known personally who was just constantly filled with poison.
For whatever reason, far fewer of them are just constantly full of malice. I knew one, in high school, who lied to her friend about me and told her I had said bad thing about her when I hadn't. But even that girl never struck me as all that evil. And I've never met a black who was into humiliating others the same way certain whites do. Which is probably I've never personally known one I'd like to see dead -- something I can't say about whites.
Obviously, blacks commit more violent crime. But it seems to be more a matter of low impulse control. And while racial politics, best exemplified by the BLM movement, may be poisonous, the vast majority of blacks I've had personal contact with have been more congenial, and lighthearted. They simply seem to be friendlier and more easy-going by nature.
Blacks are responsible for the majority of shooting deaths in this country; but you never seem to hear of one who slowly poisons her husbands to death. Or of long term Hatfield-McCoy style vendettas. Black murders tend to be more spur of the moment affairs.
Anyway, I'm the first to point out racial differences in IQ, I ought to also point out that blacks generally aren't the type to bitterly nurse a grudge forever and ever.
Update, 7/8/16: not a very timely post, I guess.
