Welcome! It's cozy here :-)
But make sure you filter out what agitates you. For many here, that is the Tankie fraction. Lemmy has a fair bunch of left authoritarian instances with users that are prone to having unpopular takes, and being very adamant about them - if that isn't to your liking, block out the lemmy.ml, lemmygrad.ml and hexbear.net instances to avoid most of it.
(But if you like heated discussions with delusional people, by all means, go ahead lol)
