I'll include the comment chains below, both the one that was alleged to violate:
1. No bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia. Code of Conduct.
And, also, the one that I suspect was more the core of the issue. I have noticed that winning an argument against Cowbee seems to be a big problem from the point of view of some Lemmy admins. Y'all are weird.
(Also, some of them hilariously enough were alleged to have violated: 2. Be respectful, especially when disagreeing. Everyone should feel welcome here.)
