Lemmygrad has a fairly standard Marxist stance. What do you count as “apoligism?”
Lemmy.ml hasn’t defederated from ATLA communities. Lemmy.world having no Marxist communities and showing signs of defederating from Lemmy.ml sends a pretty clear anti-Marxist stance, especially when they defederated from Marxist instances already.
196 does not advertise itself as anti-Marxist, but very quickly Marxists get branded “tankies” and get banned. It’s easy to pretend to support Marxists and allow Marxists but then brand them tankies if they take standard Marxist stances. That’s why it’s better to just call 196 an Anarchist instance, if Marx himself would be considered a Tankie.
