Haven't had to deal with:
"agreeing with a post, then harassed by a few comments then banned with comment deleted" with /c/vegan yet but I understand the struggle.
The vegan thing is a dumpster fire. They had a mod go off the deep end and start banning everyone.
I really don't get how people let modding go to their heads. I. Mod a few small communities and big whoop. Even if I modded a bigger one, there is a broad line between acceptable content on Lemmy and unacceptable content. Just because you have a contrary or shit take does not mean you need to be banned. Just because people are getting butthurt doesn't mean you need to ban offenders. Diversity of opinion is a good thing for a community, unless that opinion supports Nazism or some other shit which promotes hatred.
Yeah, I got banned (from a community) my first week of Lemmy on this instance just for saying I thought both capitalism and communism were wrong, suggesting something between the many 'isms" as an ideal solution. I wasn't even being rude about it.
