A bunch of people are pretty disgusting on the established fediverse as well. It's just that nobody has a way of imposing themselves in your feed.
And I don't use Lemmy, nor will I use Threads. I use services that broadcas information with both - that's different. I made a web site once, that doesn't make me a Google Chrome user. I send emails with Gmail users, but I still don't use Gmail. I just co-exist with people who do.
