Ironically, one of the hurdles that women have to face is that 'default' language is male. If you feel so ostracised that the term 'other women' is all that is necessary to completely turn you off going to a conference, imagine what it must be like for women surrounded by a swamp of male pronouns and references in this sector.
I agree, and can imagine. There is little irony in this, as I am a member of a community (Asian males) that is usually marginalized and heavily ridiculed in mainstream American culture. I have frequently been the oddball in a room who feels out of place and has a funny accent that people laugh at. Not every male who hangs out here is necessarily rich, successful, and white as you seem to imagine.
Anyway, none of this changes the fact that I wouldn't feel particularly comfortable going to said conference, and I imagine neither would most men. If this effect is intended, it's perfectly fine by me (as I have made clear in my comment, and have even laid out a viable alternative).
