Codes of conduct are just an effort to constrain conversation to a known-good state instead of attempting to achieve a state that permits all good conversation

Codes of conduct are just an effort to constrain conversation to a known-good state instead of attempting to achieve a state that permits all good conversation at the risk of permitting some bad. It's the equivalent of `-Wall -Werror -Wextra`. Your compiler will then reject some valid programs, but it will also prevent some unfortunate situations. This is just a trade-off one chooses in running a community, and some people choose one and others the other. It doesn't have to be a Clash of Civilisations debate.
