Because hexbear is full of socialists and most instances are full of rabid pro-genocide liberals.

You only got replies from hexbear haters so let me balance it out a bit. Hexbear is by far the most LGBT+ friendly instance in the fediverse and has a supermajority of queer users. They’re aggressively anti-bigotry in all its forms and are extremely happy to educate and engage in discussions as long as you approach them in good faith.

Most people who go out of their way to shit talk them in the wild are just mad hexbear banned them for saying some racist or homophobic shit

Hexbear is older than most of the fediverse, and didn’t have federation enabled for years. It’s a very self-sufficient community.
