Realistically if you tell a guy who is a stranger in public they are being a dick regarding a women it becomes super intense. Certain portion of other guys will consider you a traitor. Gillette has helped millions of guys with a relatively low misogyny factor from having to even think about stepping up in that way. I'm guessing a few million less cat calls were made last week without so much as a paw lifted.
