No aggression here, but...
Excuse me? What on earth is a male game jam?
I've never seen a single one. Go ahead, just open up ANY game jam blindly, you'll see they won't disqualify you for being a female, girl, woman, a bear, your mom.
It's hardly understandable. There is no such thing as a male game jam. Now there's a woman game jam here and it's the only one that restricts gender.
However, it IS indeed a good thing that everyone can express their creativity through art and games, etc. without limitations of one's persona. The Game Design university I went to had 50% females 50% males so there was NO minority, it was perfectly balanced. And in the end it was mostly girls that graduated. So I guess it depends on the country. But here in northern part of Europe, women making games are not a minority.
You'll be happy to know your vision of the world is misinformed and things are actually better than you think. :)
By the way I do still support the idea of this "woman game jam" because it can help inspire those more shy ones and the ones that try to avoid any male contact for some personal preference reason.
Good luck and have fun jamming!! Love! <3
