A code of conduct should be nothing more than a set of guidelines which contributors should aspire to meet. It's not a legal text, and it's not a religious text. We are free participants in projects, not unwilling subjects to be disciplined.

We've gone from projects where one was expected to behave properly, and if not would be politely admonished, and maybe kicked out if this continued over a long period, to this, where the CoC is to be used as a blunt instrument to punish transgressors. It's not an improvement, and I dislike the assumptions of bad faith and requirement for punishment. It's unnecessary, and sets the wrong tone.

"To participate in this community, you need to kill three people by Sunday"

Simple. Also, I hope you have nothing against it, since it is not enforceable.
