I think all of these statistics are very misleading. These statistics assume that all professions have equal amount of men and women, both employed and unemployed.
For example, i want to hire two scuba diver welder. In my area, there are 100 scuba diver welder, 99 women, 1 man. So because of diversity I have to hire the man. There is nothing wrong with that, right? Okey, I hired 1 man, 1 woman but this isn't complete yet. I need all kind of transsexuals... and what about all of the races? I have to hire hundreds of people to make everybody happy.
Diversity is the most sexist, racist concept of all time.
Hire the best for the job, end of story.
All-female companies aren't sexist?!
