Why is CS so male dominated?

Why do you think CS is so male dominated? My friend said it was because of the male programmers that are basement dwellers and smell bad.

Consider this: a pack of white males.
Acne-ridden, SICP reading white males nearing your boobs. Trampling your idea of hygiene. Raping you in their imagination.
And you can do a lot, since they are physically very weak. The white male leader tries to touch you and tell you about Haskell nomads. The lisp adoring males finally dominate your sense of disgust. They watch 6.001 and you are forced to run as far as possible away from them.
Such is the reason of why there are no women in CS.
