I think some women (won't say all) have been under the believe that they have the magic crotch. That once the thug gets a taste, he'll be helping old ladies across the street, feeding puppy dogs, planting flowers and giving toys to orphans. Some people are actually that silly. Of course, it's not all women. Many of them know to avoid these dudes.
Some of them think it's cool to be with these guys and that someone's going to be there to pick up the pieces because they hear folks like Deb Cooper and they think that they can do that. Truth be told, the older generation should be there to warn folks (men and women) about f'n up their future.
