And who gets to determine if I'm doing any of these things? The conference organizers? If I attend this conference, how can they assure me that I won't be at the mercy of conference attendees that suddenly decide I'm harassing them simply because I say something within their vicinity they disagree with a la Adria Richards?
Although I guess Richards would have been taken to task for "harassing photography". Although by that point it would have been too late anyway.
The problem with these speech codes is that they're just as easily used as a way to silence and shame people who's views differ from those of organizations like geekfeminism (i.e. not radfem).
You don't have to be a feminist to treat women respectfully.
