To add to what everyone else said, lemmy is basically an open source version of reddit. Anyone can create their own lemmy Instance and will have complete control over it just like any other website and can choose who they are linked with.

Lemmy.ml is the "original" website run by the creators of lemmy who are communists.It used to be an explicitly socialist website like hexbear but Its become full of liberals since people left reddit on mass for lemmy almost a year ago.

Lemme.ee is a generic website for anything so its basically like lemmy.ml but not run by communists.

sh.itjust.works is is similar to lemm.ee (a generic website for anything) but is run by reactionaries.

lemmy.world is basically just reddit. I don't recommend you have anything to do with that one.

I'm talking about the other sections of Lemmy that hate any actual leftist takes and call leftists tankies

Yeah we are on Lemmy lol. I'm just a mess

Yes. Lemmy/the fediverse is this social media platform. It's like email where there are many independent domains that communicate with each other. The biggest servers are lemmy.world, lemm.ee, sh.itjust.works, lemmy.ml, and hexbear.net

Hexbear was separate from the rest until last year so that's why people say it isn't lemmy even though it is.
