The only people I’ve worked with that insisted on code of conduct files also were the only ones that routinely harassed colleagues until they quit.

(The victims of harassment were not violating the code of conduct. This had nothing to do with left-or-right, race or gender. Instead the aggressors used their faux-inclusiveness as a shield against escalations of hostile work environment complaints to upper management. They targeted people that were more technically competent than they were.)
