I'm actually being placed on the other side of the fence here, I don't have a clue what "gender discrimination" looks like in the broader tech world, all I know is that in my company, the techies are equal in numbers, male and female (thought not of course by design.)

I find it sad that I often see a great group of people and a group which I would absolutely love being able to join, but that it is exclusively for women, is this really how we want to solve a perceived gender discrimination? By creating another one which leans the other way?

So often politics of gender, race, sexuality, etc. seems to over shadow what these groups should really be about, which is bringing people together to learn and have fun experiences. Men and women can have these fun experiences together, we don't need to invite purely men or women, imagine the backlash if "blokes who code" had a male only tech group.

It's very easy to play the "under-represented" card, but the fact of the matter is this: women in the U.S. ever so slightly out number men. There is absolutely nothing stopping women joining in with the tech industry, there is no law, no patriarchy standing in their way, the only thing stopping a woman from joining the tech industry is herself.
