Of course they're not entitled to get anything, but a reasonable person doesn't continue performing the same action when it benefits them in no way. There's nothing irrational about a man not going out of his way to befriend women in the workplace because he's had bad luck doing it, or because of the risks he's not going to have befriending other men.

If you have a lot of women as friends, that's great. Your experience is not the experience of a lot of men. A lot of men can't relate to women on a platonic level, and that doesn't mean they're misogynists.
