What bugs me is the fact that no one is complaining about low presence of men in female-dominated industries. But god forbid if there are 10 male programmers and 9 female ones, DISASTER!
Try 1 female for 40 male programmers (That's about the ratio in both my internships, as well as my Software Engineering bachelor's degree group) and add to that the wannabe cool guys making sexist jokes in their public announcements and you might be closer to the current situation.
It's just the blog-people I ever hear raising this issue.
Do you actually know that?
