Ignorance I Think

Well here is my random thought of today. A few years ago I was talking to a man I knew and he said something that upset me. He said "if a women isn't pleasing her man at home he has the right to cheat." I was taken back and thought he was just trying to rattle my cage at first, but no, he was very serious. Then I wanted to punch him in his ignorant pecker, but I don't think that would have gotten the point across somehow. We continued to argue for a few minutes, I was offended as could be. I have been cheated on in the past, as I'm sure most of the world has, and it hurt to hear something like that. I hold true to my stance on this statement to this day, but really, do people actually think like this? I mean both women and men, it does go both ways. I am curious to know how much of the population has this sort of mentality. Seriously!
