Guys, want to know how you can help change these kinds of attitudes? When you see/hear another guy make these kinds of comments, pull them aside and have a talk. Maybe it's a gentle reminder of how hurtful and counterproductive these kinds of attitudes are, or maybe it's a forceful "I never want to hear that shit again" - depends on the type of personality you're dealing with. Regardless, you need to have the difficult conversations with friends or colleagues who act this way, because turning a blind eye and ignoring the problem doesn't help anyone.
