i think one of the problems with Online Leftists is that the loudest of them is mostly white people who haven't had to deal with social injustices since they were children so you get a lot of people going "WHY IS NO ONE TALKING ABOUT THIS" when everyone darker than beige knows and has been for years
i also think that white people only think that other white people are constantly posting and they have a lot of liberal guilt and so they take it out on everyone
but that's just my thinking
