Hi,
I remembered how readily "the guys" assumed that any woman there was there
for more than just networking and learning. I remembered having my butt pinched, my breasts "accidentally touched", my questions ignored or laughed at. I remember how the buzz of background conversation is always much louder when the speaker is a woman than when the speaker is a man.
All of these behaviors fall somewhere on the spectrum from rude to depraved, but am I correct in thinking that most of them would not actually be covered by a code of conduct? Ignoring or laughing at someone's question, for example, is certainly rude, but I can't imagine anyone getting officially reprimanded for it, unless there's an additional element of confrontation there. (I don't know if this happened at a talk or during an outside discussion, but either way I'd think it's the same.) Certainly neither the Wikimedia code of conduct as currently drafted nor the WMF Friendly Space Policy cover simple acts of rudeness, even if motivated by bias.
