Sorry to hear about such a discouraging experience, Christina. I’ve really been getting my eyes opened to how pervasive, deep and insidious the problem is lately, in part thanks to Emily Rose (https://twitter.com/nexxylove) inspiring (challenging) me to do a bit of soul-searching on how to be more inclusive. I’d say a big part of the problem is that no one really realizes they’re part of the problem! We’re worried about bandaids for behavior instead of changing attitudes that affect behavior at the onset. Effecting social change is hard, and trying to do that at a technical conference has got to take some real guts and a thick skin. Don’t give up (and I suspect you won’t)!
