u/firemonke8 brought up the word "bourgeois" and that's exactly the right way to frame this. It's derived from marxism, whether intentionally through academic theories, or purely by playing on social group dynamics:

This is a process that hijacks individual empathy and uses it to discriminate and scapegoat others, in the service of the "oppressed". You just need to continuously redefine who is oppressed, and use that to build "allyship". You think Lenin himself was oppressed? No way! But it worked to get himself and his thug buddies in power, didn't it!
