I'm ready to believe in a conspiracy theory around codes of conduct, actually.
Except perhaps where there are too many contrarians, folks looking for a problem, authors who are being intentionally vague, or acts of malicious compliance.
A member of the Somalian community instrumentalizing anti-black and anti-Muslim feelings to boost the standing of his own group, and the Code of Conduct fails to protect academic freedom. Well done!
I still prefer communities that document their rules and expectations over those that don't.
This isn’t universal as some people may be grateful if you approach them tactfully and let them know that others are having difficulty with them, as they may not have realized.
To be frank if someone has driven others away I feel an obligation to to the rest of the group not to shrink from addressing the matter. People whose participation is a net negative because other valued participants flee from them shouldn’t get endless opportunities to make others miserable.
