men's rights advocate
My friend and I were telling her boyfriend a few weeks ago about being harassed in places like the grocery store, the mall, on the street, in the bank, at a restaurant, etc. etc. etc. and he was horrified. This is because he is a good person who's never thought about doing that to another person. Then I asked, "Well, what do you do when your friend catcalls someone?" and he said he gets very embarrassed. But he didn't tell the guy to stop.
