Here's a theory of what's going on:
Remember the 1984 movie Revenge of the Nerds? It was made in response to what was going on at the time, when nerdy Bill Gates types were figuring out how to leverage math and science to gain power.
Now a couple generations later the math and science nerds control everything, and people who can't or won't do it are feeling crushed by it.
So the SJW/CRT/BLM movements are a form of Marxism where the Proletariat are the people who can't do math and science. And so part of what they are demanding is almost literally canceling math and science. So...Revenge of the Morons?
