Most humans grasp this, that this behavior is counterproductive. Most older blacks, caribbean/african blacks, and blacks raised by families that did everything in their power to turn them into good, responsible people seem to get this. This attitude seems to have been specifically cultivated among a group of people that welfare is designed to keep in place, shitty schools are designed to make unemployable (kept that way by teachers' unions), and for whom onerous laws such as mandatory minimums seem to constantly deprive of male role models for minor drug offenses since the 90s...
I don't agree that schools fail black kids by design, at least not in the way you're implying.
Black majority schools fail kids because most of the kids and parents don't care about doing well. The number one factor in educational success is parental engagement, both because it's really only parents who can hold their kids accountable and because schools need a robust PTA to fill in financial gaps since there's never enough money from the government.
Some of the kids and parents are motivated to succeed, but if enough kids/parents don't give a shit, it becomes impossible for the motivated kids to do well. The majority of badly behaved kids who don't care mean teachers can't control the classroom. I used to tutor kids on the Lower East Side, and they all complained that their classmates would yell and throw things and be distractions in class all day every day.
The motivated kids technically pass their classes since they turn something in and try to take their exams, but they won't actually have the skills to succeed, not without a ton of remedial learning at the college level.
The way that schools are set up to fail black kids is by setting the bar so low it's through the floor. I could see teachers' unions playing a role in this since low standards also benefit shitty teachers, but I still think it's mainly white guilt and "benevolent" racism that's to blame. Although I won't be sorry to see teachers' unions fuck off forever.
I'm not sure where these leftists find these put-together, polite, mature black people to befriend but I wish they were a far greater portion of the populace than they are. Maybe Minneapolis wouldn't have turned into Mogadishu in four days if that were the case.
Black people like that are the only ones capable of working in white collar jobs, so that's your answer for where white libs find them.
In related news, CBS is promising to have their writers be 40 percent black and indigenous which is going to be categorically impossible unless their affirmative action hires are people who are in no way qualified for the job in education, experience, or temperament. (It would be difficult enough to get the number to 15 percent since black and indigenous Americans are much less likely to go to college.) My assumption is that CBS will just give up, which is too bad because it would be hilarious to see the fallout.
How did they express hate towards black people? Lefties are rarely blunt about that stuff, right?
They're usually not blunt. It's more subtle, such as their belief that black people are too stupid, lazy, and violent to succeed in life, which leads white libs to categorize the basics of success as "white supremacy".
