Somebody can correct me if my timeline is off, but I think Lemmy was largely embraced by exiled Chapos, much like Voat became a Groyper den.
I don't think it's even worth considering such a community left-wing. They're more like an anime poisoned grooming circle that embraced red aesthetics for shock value.
However pathetic that sounds though, I'm the bigger loser for even being familiar with this nonsense.
