You need a code of conduct when you have 2000 people drinking in a hotel, having parties etc. Someone is going to be an asshole and having policy ahead of time means you don't need to think of a solution on the spot. It's a fair system.
Read it here. It's pretty low key for a code of conduct.
Didn't those use to just be called "the rules"? I think a lot of people's resistance to a CoC is that it's a Dog whistle for a lot of the issues discussed in this post.
Edit: Instead of down voting me, rebuttal the idea. CoC are on their face not bad, but in my experienced are pushed by people with other agendas.
Is there a better word/phrase? I purposely used "dog whistle" because of the political connotations as a signal that implies more than just what's on it's face.
