As someone on .ml I really don’t think it’s that bad. Definitely left, and generally pro-China, but not too extreme imo. Hexbear is pretty bad. I’m a socialist and I disagree with a lot of the stuff there. But .ml is very much not a true “tankie” instance, in my opinion.
Oh yeah, and it makes total sense. The brigading, insofar as it happens, really shouldn’t. But also, as someone who espouses left wing views, I always want to give critical support to left spaces - even if they’re imperfect. And .ml and even hexbear have a lot of valuable discourse - I comment on hexbear threads regularly with less radical points of view than their users often have, and I get good responses and engagement usually because I’m good faith.
