Reddit

"I did something pointlessly mean and insensitive, but that's not important! I experienced repercussions that I feel were undeserved! I demand justice (but only for me, not for anyone else)!"

I get what you're trying to say, but you're choosing a rather tactless way to say it. Point is, that community is run by moderators who are exercising their right to ban you based on your choice of speech. You could send the moderators of the community a DM, apologize, and try to sort it out, but instead you're coming here to complain, which is... definitely not going to solve the problem.

Alternately, start your own AskLemmy community elsewhere. If enough people disagree with those moderator decisions, they can come and participate in yours, instead. That, really, is the benefit of Lemmy over Reddit.
