Stereotype was probably a bad choice of words on my part as it has inherently negative connotations. What I'm saying is that there doesn't currently exist a Computer Science "image", or idea of what it is like to be a Computer Scientist, that is friendly to women.

I'm just using the logic behind how it would be ridiculous to say that the frat boy image is putting women off from joining Greek organizations (beyond having to interact with them), as most women who are thinking about joining a sorority probably aren't worrying particularly much about becoming a frat boy.
