Nice guys is kind of subjective, for instance when I met my now wife she was seeing someone else (and had been for 3 years) that didn't stop me pursuing, wooing and stealing her away from him. Now at face value I probably wasn't a very nice guy to do that but my wife would describe me as a nice guy.
I think there's also a bit of a instinctive thing going on, we are all animals after all, I guess bad boys seem more like the alpha male pack leader sort and women are instinctively more attracted to them. In the same way most men are instinctively drawn more to women with big boobs and hips because the primitive bit of our brain tells u that means they would be good at child bearing.
People shouldnt be afraid of their Governments, Governments should be afraid of their people.
