Mastodon/ActivityPub is not Twitter. It's not millions of people in one stadium. It's more like dozens of rooms in a big mansion. (sorry, the analogy isn't perfect) ... You don't just walk into the room with a bunch of nazis because that place is probably going to suck to have a conversation in. Look at what the conversations and social expectations are before you jump in, and things will work out a lot better for everyone. That's not a bad user experience, that's just "socializing with fellow humans".
