It really isn't, but we can understand why people might feel that way. We've found that by having a women-only space for learning Python and Django, women are more comfortable participating. See this essay on "reverse sexism" and Rails Girls to see what we mean. If you're having the knee-jerk reaction that reaching out specifically to women hurts men, or hurts diversity efforts in other areas, we encourage you to read How I Stopped Worrying and Started Loving Pyladies by Hynek Schlawack. One particularly relevant quote is this:

Outreach programs don’t divide our community. They incubate people which aren’t comfortable to cope with us from the beginning on and grow our community in the long term.

It doesn’t really matter whose fault the initial discomfort is. Whether they’re being over-sensitive (hint: they aren’t) or whether we’re a bunch of a**holes (I know you aren’t). The facts are these: if we want underrepresented people to enrich our community, we have to look for pragmatic ways to get them in. Even if the methods don’t seem sound to us on the first sight to us.

“Yes, but…” discussion don’t help. PyLadies – and similar outreach groups – found a way that works. So be thankful to their organizers for doing this! And again: if you know of a better way, stop sh*tting on their approach and go for it! The world isn’t binary; the more approaches, the more diversity, the better.

Also, not all Django Girls events are exclusive to women. Our organizer's manual encourages organizers to use our materials to put on workshops for women and for mixed-gender groups. We've also open-sourced all of our content, so if you like our tutorial but don't want to put on a Django Girls event with it, feel free to fork it, credit us for the content, but rebrand it into something that works for your goals.

We don't want to get men out of programming; we just want to bring more women in. There are already a lot of other bootcamps, workshops, meetups, and groups that are "mixed gender," but are really mostly men. We've found that by limiting our workshop to a majority of women participants, women are more comfortable signing up, asking questions, getting involved, and even staying involved later on. And that's a good thing!
