It's the anti-KKK. They grew up learning racism is bad, which is absolutely true. But people were so freaked out by the past that they pounded it into these kids hard enough to fuck up a few of their circuits. Now we've got a bunch of people who are positive that being white is bad, because white people do bad things because they're naturally bad. Any society is always going to have it's massive fuck-ups, but the course correction might have gone a little too far to port this time.
White people being 65% of the population in the USA and representing 100% of the government is probably a sign that something's wrong. Unfortunately now we have a very loud and passionate group that believes that 35% of the population being black means 95% of the government should be black. The obvious talking point is that so many people are willing to abandon the idea of merit in favor of some abstract sense of balance, and how terrible that would be for our species in the long run.
But I think the bigger problem is just how terrible your average person is at math. I can forgive emotional instability and faulty strategy, but I can't make an excuse for bad math.
