Even if you disagree with them, Trotskyists are not tankies, simple Marxists aren't tankies, leftists curious and exploring different theories aren't tankies, and ffs anarchists like myself are not tankies.
I feel like "tankie" indicated a very specific worldview at one time, but it's been used lately a lot to mean things like "doesn't agree with nations supporting oppression and inequity up to and including genocide" -- which is drastically at odds with how I've seen the term used in the past, no?
If their moderation can't keep up with it and they become a Nazi bar, then yeah. For me, I have consistent experiences with .ml users in that the vocal ones support oppression of minorities up to and including atrocities, deny historical atrocities in a manner similar to antivaxers/flat earthers/etc, and generally smell like a creepy cult. If those are the users getting noticed, those are the representatives. If their mods condone that, then I don't think the problem is solvable on a per user level.
