Now, I can understand some of the reactions, from both men and women. On the one hand, I can see why guys might say "isn't this just a different form of sexism?" and I can see how even some women might be offended (the same kind of women who freak out if a man holds a door open for them, probably). But despite all that, this has a chance to get more people involved in, and contributing to, the F/OSS world. For that, I think we can accept a small measure of "reverse sexism", given the context, and I think the radfem types can like it or leave it, while their female peers are busy writing code.
Yeah, it would be nice to live in a world which is more or less totally gender-blind, but we're not there yet and this move may at least help level the playing field a little bit.
