it's like solidarity amongst the lower classes only matters up until the point when you have to start working against the oldest arbitrary division that's been used to keep us from organizing

Unfortunately, I think a lot of the read theory bros on lemmy are people who are less concerned about solidarity with the lower class, and really just involved in Marxism because they want to abolish class because they've incidentally fallen into the lower class.

There seems to be a lot more anger about their own displacement within their own society than the plights of more disenfranchised minorities classes. I think that's why a lot of the Marxist/communist instances are so obsessed with the particulars instead of being a more big tent community.
