But also (and this is my main issue with such points) CoC are a reaction to things that went bad, and an attempt to fix these issues.

I briefly talked for a time with a guy who knew I had life threatening respiratory problems and he tried to talk me into meeting him in person, while swearing my health and welfare were his highest priority and intentionally leaving out the fact that he was a smoker and a toker. When it finally came out in conversation, I had a cow and he pulled this nonsense about "If it is that important, you should have asked."

Um, no.

I was so upset by the whole thing, I briefly considered putting something in my profile on the forum where we met specifying "No smokers, no tokers." Then decided this is about as useful as putting up a dating profile that says "No rapists, no pedophiles."

He knew it was not acceptable. This is why he hid the information. Any BS justification for his behavior after the fact is just part of the headfuckery.

And, unfortunately, a lot of CoCs seem to be along those lines of explicitly forbidding behaviors that we already understand are bad, as if that will somehow stop people who already know what they are doing is not socially acceptable.

The areas where people are oblivious due to entrenched prejudice of some sort will not be fixed by spelling it out in some detailed list.

We are catering to the lowest common denominator by spelling out what is and is not acceptable. This isn't a means to foster a civil environment.
