What a brutal, stupid, ahistorical take. Race hierarchies weren't created by the left, the left merely identified them which upsets delicate flowers like you.
The entire concept of race is stupid. Yes I assume it was created by the right, or at least by racists. We need to destroy the concept of race by treating everyone the same regardless of what they look like. To do this we should judge individuals by their actions, character, and merit instead of their skin colour. When I go to work I don't treat some people better or worse based on their race or gender. This is the way we were moving since the 60's but I think those doubling-down now on identity politics think changing everyone's minds over decades is too slow, they want the changes to happen right now, which just isn't possible. Sometimes unfortunately the only way to cure a racist is to wait until they get old and die.
I don't think "white people" are the problem, which is what the woke say these days. The problem is individuals who are racist. Blaming the individual or policy or organization is a lot healthier than blaming an entire race, because this leads to racism towards white people, and many white people are naturally going to get their back up to these racial overgeneralizations and scapegoating and fight back in kind. Most white people can get behind the idea of condemning individual white people who are racist, we had been doing that as a society since the 60's. But when you say "white people are racist" instead of "this individual white person is racist for doing X" even a lot of the good white people get their feathers ruffled with that one, except those dripping in racial guilt for things that are the fault of others.
All racial overgeneralizations are unproductive if not socially destructive.
