Literally anywhere that isn’t lemmygrad or hexbear will usually be better. You could go to an instance with open sign up until you find somewhere else, but they tend to house a lot of closeted reactionaries, I assume because those people like the anonymity. Personally I just looked up instances to see which ones I liked. They’ll have a description of who they are and if sign ups require an application you just say why you want to join their instance. It’s not a huge deal really.
