Lemmy as a whole is pretty staunchly left and tolerant generally. Looking for things flagging themselves left here. Implies looking for the left of the left. Which ultimately leads to circle jerking and edgelord virtue signaling. It’s a bad time. Left can mean different things to different people. Drasticly so. If you consider yourself “left” look into some of their philosophies and see what resonates. Then look for communities based around that. You’ll likely have a much better time. And learn things in the process. Win win.
Boiler plate comment
Marxist Leninist aren’t communists. Or they wouldn’t be Marxist Leninist. They do however like to cosplay as communists. Often naming things that aren’t communist Communist. While I think the general proletariat were all aspirationally communist. Their leaders and the Vanguard party most certainly were not.
