Leftism's Inability to Recognize Differences Between People

leftism is so concerned with creating a society of at least material equality that it also has tended to really militate against the acknowledgement of inequalities and other aspects of human experience. I do think that material inequalities in the biology of aggression per se territorialism intense hierarchical accumulation um outright aggression towards one another war incarceration things like that are fundamentally incompatible with a survivable form of society. So there is some sense in which the right left political spectrum does imply the space of question of you know if people are fighting for more or less equality what are the other perceptual biases that people who want equality have?
