I'm surprised it's not more widespread (and still newsworthy)
I remember once finding myself in the gaming room upstairs from a game store, on a night out. I think we'd gone to collect the husband of one of the women in the group. The rules posted at the entry were one long list of stereotypes, from personal hygeine to respecting women.
This is, of course not exclusive to nerd culture. We have to treat our footballers like children and send them to "respecting women" classes too.
