Can someone teach me how to handle the replies in that article about bros and slut-shaming? Because I can't.

My friend just got home and Gchatted me that she was being followed most of the time by a guy leering at her. I'm on the other side of the world so I put on my Planned Parenthood shirt, grumbled, read that article and the comment thread, and decided I don't have enough alcohol within reach of my bed.
