Men understand that.  Even hardcore rapists understand that, they just ignore it.  The idea that "men just need to be taught not to rape" is insulting and demeaning.

 What women need to understand is that a man has that right, too.  As well as the right to avoid a situation that puts him at higher risk of false accusations, such as college.  It's interesting, a woman's chance of being raped actually go down when she attends college.  Whereas a man's chance of a false rape accusation goes up dramatically when he goes to college.  So factoring that risk into the decision to skip college in favor of trades is just good thinking.  If that means we'll have yet-another generation of women who can't find suitable husbands, so be it.
