Are we? Got specifics?
One assessment says
1 in 6 women suffer from an attempted or completed rape, even if this is off by half a magnitude, that tiny percentage of men get around! I get this feeling women are experiencing one thing, and guys are seeing something completely different. Man and woman walking out of movie theater.
Woman: That was a great comedy.
Man: Yeah, I love race car movies.
Woman: *wah?*
Women are complaining, a lot about this.
Women: Sexual harassment and assault is much more prevalent than you think!
Men: Naw... it's just a small percentage of men.
Women: *wah?*
Heck, you even said all men are capable of rape, but then simplified it to a tiny percentage commit it.
I don't think talking to boys more about it will bring down rape numbers one iota.
You haven't even established that they are being talked to enough about it. When these things happen, it is all about what can women do to make themselves safer. Not what can be done to reduce attempted assaults.
