I love men talking about women issues from their own perspective. You cannot assume the situations of the industry in every country, although is great that in your Uni there´s a lot of women making videogames, it is not the same in the rest of the world, just check the recent scandal of Activision Blizzard systematic abuse and harrasment against women.
And just for your information the jam is not exclusive for women even though the ideal would be just for women, there are a lot of men participating in the jam. So no, we´re not sexist.
