I also disagree with him about CoC&#x27;s, though for a reason that he doesn&#x27;t really address.<p>Anybody who has lived for long enough knows at least one person who can be unkind out of obliviousness, not knowing better, or not being aware of social cues.<p>Also, people in disagreements get mad or passionate, and that tends to incite people to cross the line of professional respect. Passion is good, hostility is not. I&#x27;ve had to remind normally kind people that I manage to &quot;not do ____ again&quot; on multiple occasions, with the implicit threat of firing them.<p>My conclusion from my own experiences is that &quot;don&#x27;t be a dick&quot; is not universally understood, and people will make mistakes, often unintentionally. So I think a CoC is useful as one of many different ways any organization has to remind its members to be kind. It&#x27;s still up to the administrators to enforce things, but a CoC is a useful reminder especially to incoming members to be aware of their conduct.
