Too many people are confusing the two. Whenever lemmy.ml or its devs do something stupid, people go “Lemmy is getting worse and worse,” or “I’m leaving Lemmy,” or worse, “I’m leaving for Beehaw.”
If you’re using Beehaw, then you’re using Lemmy. Lemmy is the software these instances run on. If you don’t like lemmy.ml, join another instances that have rules that match your philosophy. Some instance hosts authoritarian or fascist shit? Turn to another Lemmy instance. Lemmy.ml is not even the biggest instance. People who just joined and are unfamiliar with the platform will just think the entire Lemmyverse is run by autocratic admins if we don’t get our terminology right.
The fuck is a tankie?
I don’t think there is a clear and consistent answer to this question. Like asking a conservative what “woke” means, it is used to refer disparagingly to a wide variety of people that a given person doesn’t like.
From usingenglish.com. Originally a western communist who supported Stalin’s authoritarianism, usually backed by tanks, the modern tankie supports pretty much any authoritarian government or dictatorship that opposes the West.
