Suing to Keep Away Men

I'll admit right off the bat that I don't understand the mindset of someone who would care about going to a single-sex college. It doesn't seem that these places are bastions of feminism and they don't look like finishing schools. Is it the image (my sister once said that all-women colleges were "preppier")?

I suppose it's no goofier than a male-only priesthood but shouldn't an institute of higher learning at least make a token show at reason and logic?
