It's a lesson that doesn't seem to get learned, even after decades of research saying that people start internalizing negative stereotypes, 'reasons' they have been abused, and statements indicating low expectations of them. When people hear 'math is hard', many people don't even try to learn it. When people who consider themselves part of 'group X' hear 'group X is bad at whatever', they don't do 'whatever'. And when 'group Y' hears that they won't amount to anything, many just give up trying. It's destructive, it's horrible, and it is real.
There are a few important things to realize here. Some of those who say these horrible things often don't understand the topics very deeply. As a former, and still peripheral member of various social justice 'communities' (and I quote that because the 'communal' part is often centered around unfocused anger), I see and have seen so many people come to discussions with only talking-point-level understanding who run with it (or are simply running on 'cached thoughts', rather than situational ones.) The other thing, which the author likely knows well, is that in the Oppression Olympics, the author is in the biggest loser group, so is going to be cared about the least. Despite endless blog posts and pleas to end the OO, internecine attacks, ally-bashing, purity tests, knee-jerk responses, and all the other wonders of the SJW world, it goes on. I don't blame the author for exiting. It's part of what made me sideline myself, and many other former dedicated members of these communities.
