Well that's easy to avoid- don't give anyone ammunition with which to dismiss you as an asshole. It's totally unrelated to whether or not someone really is an asshole. It's trivially easy, and if it's not trivially easy, well that's a big giant glowing arrow pointing at an impending personal growth opportunity with a reward:effort ratio that's off the charts.

Whether or not someone is an actual asshole, the ability to avoid misunderstandings is critical to moving forward and getting stuff done and not wasting time on distractions and petty arguments. CoC's are simply an organization's defense mechanism against pointless interpersonal chaos that doesn't belong on their mailing lists (or whatever) in the first place.

Source: genetically inclined to be a total and complete asshole, have spent the last few decades trying to get better though.

Why not just say that, then?

Basic courtesy and respect doesn't need much of a list.

This is a long list of codified norms du jour to launch endless power micro-games and let attention-seeking holler than though people to run the show.
