Memes

Not exactly. This started yesterday, when a user accused mods on .ml of, "tankie censorship," (meaning censorship by tankies, not of tankies). He also came with some pretty good receipts that appear to show .ml mods removing criticism of China that, whether you agree with it or not, didn't seem to violate any rules, and was well within the bounds of what most people would consider civil discourse. He also claims to have received bans from all of the .ml communities he'd ever participated in for pointing this bias out. It's possible he's presenting all of this with his own slant, but what he showed seems legit, and I'm not sure he could have provided more evidence without encouraging brigading.

This is now starting to snowball, with users starting to call for defederating from .ml. One .world user also posted on .cafe about Dessalines previous tankie comments, while another user has posted about finding replacements for the largest .ml communities.

So, saying what's happing on .world is anti-communist isn't accurate, as most the criticism has been anti-tankie. However, .world has a much higher level of liberals than most of Lemmy (they created a little echo chamber for themselves on Political Memes), and most of them are incapable or unwilling to understand the difference between a tankies and communists (or tankies and leftists...or tankies and criticism of Biden...). So, it will probably only be a matter of time before this group tries to blur the line between valid criticism of baised moderation from authoritarian apologists to general criticism of leftists.

So, tl;dr: .world isn't broadly anti-communist, but a large portion of the community is upset about what appears to be biased moderation from tankie .ml mods, and there is a small contingent of .world liberals who I'm sure will take this opportunity to bash anyone to their left.
