I think it honestly goes beyond that.
There is a fucking dark mindset underpinning a lot of the crazier lefty elements out there. I first started noticing it in the SJW community on Tumblr, and I called it out for what it was back then, but essentially, they've replaced the conventional definition of racism with one where only one race can possibly be guilty of it - where they feel the correct solution to racism that happened ages ago is more racism, but by the right people this time.
If you look past the people who were doing that back then, cursory analysis of them showed you the real reason they were doing it: It wasn't just them being taught shitty lessons - shitty lessons are a problem but they do not, in and of themselves, create shitty people like these. Instead, it was the pathological need to be morally superior to someone. It shows a stunning level of insecurity and immaturity, existing solely to allow the shittiest possible people to be dicks to others with the full support of their conscience
