Replace “Lemmyverse” with “the American left” and you’re closer to the truth.
The American left is against racism … yet harbours an alarming amount of antisemitism and an increasing amount of sinophobia.
The American left is against ageism … directed at young people. Old people are open season.
The American left is against religious bigotry … except Christians. . . .
It’s just tribalism cosplaying as idealism. (And it’s why, for example, Chinese LGBT groups have been quietly removing themselves from interaction with American LGBTQA+ groups over the past few years.)
