You asked with a .world account, meaning you’re defederated from 2/3 biggest communist spaces on Lemmy, on Lemmy.ml, the last third. As such, it became quite a mess, because communists are outnumbered by anti-communists if you cut out 2/3s of communists.

The ones that had their comments removed were picking a definition that does not correspond to reality.

It’s kinda like asking what the word “woke” means. MAGA people are going to give you this elaborate strawman, and others are going to tell you that it’s just a pejorative strawman.

If you want to see all sides, read the wikipedia page for “tankies,” first, as it’s the liberal understanding. Then compare that to the prolewiki entry for “Tankies,” for a communist perspective on it, then read “Tankies” by Nia Frome to get someone to elaborate on how it’s actually used today, beyond its origins and the strawman characteristics it holds.
