I remember so many comments like that back when I worked in systems. Once I was talking to a guy from a vendor who kept asking for my "network address". I asked him if he meant IP address or Mac address, and he said in his incredibly patronizing voice "Your *network address*. It looks like a number, followed by a dot, followed by a number, followed by a dot... look, can I talk to your technical guy?"
I hung up on him and called his manager. His manager spluttered and groveled a lot. It felt good.
But that was professional technology. I'm not saying there wasn't a lot of miserable sexism in professional tech, but at least they were always managers who would splutter and grovel, you know? In open source somebody makes comments about virgins (and *yes*, I wasn't there, but here's another woman who has seen record of what was said and is incredibly offended by it), and he keeps getting invited back to get more and more speeches with the same joke.
