Oh just seeing now this was a reply to a thread... catching up...
I wish I knew what to say. Obviously I care about you and want to see you do what makes you happy, and I wish that meant not leaving the fediverse.
The only suggestion I can think of is to start new. Create a new account and dont tell people who you are other than a few people you might trust. Then maybe people will leave past mistakes behind you.
I believe in forgiveness. If a person said or did something that hurt others, and they recognize that was wrong and try to change, then I will absolutely respect and support them. I dont know what it is you did in the past or what specifically people attack you for but I am sorry they arent focusing on who you are rather than mistakes you made.
I can understand and relate tot he liberal thing as I saw some of that too. I tend to be centrist with a slight left lean. This generally gets me a lot of hate from a lot of sides and the FSE crowd I know you have a connection to often is very intolerant of views that arent on the extreme end of the spectrum. I saw alot of them go from praising me to talking shit on me too. Luckily for me I never really had much respect for the way the FSE crowd handled themselves so it didnt effect me much. But I do understand if people like them and others on the fedi (like POA) attacking you for liberal lean might be very painful.
I guess ill just ask, is there anything I can do to help you whether that means you leaving or staying, if I can help I'd be happy to do so.
