It's one of the largest and one of the easiest to join. I'm certainly not going to suggest Pawb for 90% of people unless I know they are a furry, and I would never recommend .ml. SJW would be second, and I might suggest db0 if it doesn't make you fill out an essay to join (I haven't made an account there).
Addendum: Yes we know that you think ml/hexbear/grad are tankies and or .world are a bunch of liberals but it gets old quickly. Try and come up with new material.
This is not the place to start flamewars between Lemmy, Mbin and Piefed.
