Welcome to the late '60s all over again. Where I grew up, white teachers and administrators would not discipline black students for fear of being branded "racist", and discipline broke down. Black teachers and administrators with rare exception were slow to discipline white kids, for fear of backlash, even though even incompetent black teachers were 'safe' from dismissal because of the political appearances and potential to provoke a riot.
Race riots were the order of the day in schools where the mix was close to even, and despite a few good teachers' efforts, getting anywhere academically was a serious struggle, even for the best 'sections' of students (grouped on a basis of percentile rank on standardized tests like the Iowa Test of Basic Skills). Sections with higher numbers (and lower scores on the tests), had even more trouble.
All this followed forced integration by 3-4 years, with plenty of outside agitation (one student was arrested in school by the FBI for his associations with H Rap Brown, Stokely Carmichael, and Eldridge Cleaver and incidents in Cambridge, MD).
Thankfully, I had the opportunity to go to a private school by my junior year, and I jumped at it. Academically, it saved me.
So how about this: restore the ability of teachers and administrators to discipline students, expel them, suspend them, as they see fit.
Quit playing numbers games with how many of who of what skin color get in trouble and start dealing with kids. Take 'em as they come, and don't let them off because they are black or brown or white.
They aren't dumb, they will exploit any weakness, especially kids from homes most would consider 'rough', because that is what they have learned--to survive in a dysfunctional environment, by whatever means necessary.
Essentially, the Liberals got their wish, the village is raising the children, but the results aren't the shining vision of warm fuzzy utopia they envisioned. They've created a dystopian environment full of subsidized ferals who see no gain in playing by the rules because the libs have told them that the deck is stacked against them so often they believe it, and besides they'd be pulled back into the crab basket for trying to climb out and 'acting white'. Even good kids end up having to be bad to survive, and gaming the system is seen as a superior adaptation, not putting out the effort to learn and thriving within it.
