The rules end up there because people complain about things and then the mods implement a rule to ban the things people complain about. Sometimes they let the community vote on it. It does end up being the vocal minority who the rules cater to sometimes.
And they have to be more or less vague to give the moderators room to decide if the rule breaker did it by accident or is just an asshole. Trolls will do anything to walk the fine line between not breaking the rules and being as annoying as possible.
I mean…there’s very good reasons to respect the wishes of minority groups sometimes (not always). It’s the reason they wrote the “First they came for the communists” poem.
