This is only one example. Many single-sex female institutions fight and have fought against going co-ed for similar reasons.
And I agree. When it comes to developing the mind, I would prefer an all-male college. When it comes to developing the body, I prefer an all-male gym. It's only when I want to socialize that I will hang out in mixed crowds. I think the reasoning behind this is obvious and so does Mary Daly.
But you feminists can't have it both ways. Stop harrassing and suing all-male institutions and clubs, you hypocrites!
