I support codes of conduct, for multiple reasons stated and not in this thread.

I do not support putting words into someone else's mouth, particularly on socially explosive (hence the discussion in the first place) or ideologically driven issues.

Asking if someone's ever been harassed is one thing. Stating point blank that they haven't, crosses a line. Your interlocutor knows their personal history. You don't. Don't presume. It's a cheap shot, often derailing.
