FWIW, Twitter (not saying Twitter is the best or only site) allows you to have a feed of only people you follow. That probably approximates going to another site of only people who share your core beliefs.
It doesn't matter if you interact only with people you follow, given that anyone with a bit of an audience gets plenty of hateful replies.
There's a concept of "background radiation" expressed in social spaces. Dealing with a constant barrage of people who hate you or your existence[1] is tiring.

On Twitter, I have a make an active effort to not click on the "For you" tab because I'll be bombarded with posts about Trump or "woke" games, which I simply don't want to see. On Bluesky, I can actually discover new content without having to think about my mental health when using the "Discover" feed.
