I wonder if other men sometimes react with "don't you love the attention?" because (A) they wish they got that attention from women and (B) they want permission to be able to "approach" women the way the aggressive dude is. Occasionally there is (C) guys who see the intimidation tactics for what they are and pitch in to discourage aggressive guys. One thing my husband has told me is that bullies bother other men, too--and they aren't sure how to react either. So they do nothing, minimize, or deny the threat. Males who treat women like this bully men as well and most people are not comfortable confronting bullies.
