If you figure it out, let me know ok? I do think I've figured one thing out. When I was younger, I always liked the guys who were a little bit wild, didn't care too much about school, the musicians and artists and bad boys. Now when I see the guys who have turned out well; who have good kids, happy marriages, and responsible jobs; lots of them are the boys I thought were boring in high school. So don't ignore the nice guys just because they don't seem interesting or sexy. The high school bad boys sometimes turn into alcoholics, addicts, or cheating husbands, and there's NOTHING interesting or sexy about that.
Good question. My take is that guys mistreat girls because of what they first observed between their parents at home - dysfunction - and media/social pressures to demean females. You see this a lot with parents that have an autocratic domineering father and a servile, submissive mother. Once primed by this early exposure, media reinforces it - not always - but typically - guys are portrayed as arrogant and not very bright that only want one thing from females while females are game players that confuse males. These stereotypes didn't just magically appear - they are based on cultural norms - in more regressive cultures - the ratio of good guys (respectful to women) to the herd of the rest is even worse. The underlying reason that these males (the bad guys) behave as they do has been speculated by sociologists that males fear females on some primal level - biologically the male is the active participant in procreation - the female is necessarily submissive - even though throughout the whole experience this may not be readily apparent. Rejection of the male based on his reproductive prowess is a fear males carry within their subconscious. One way to combat this fear is to demean the female to the point where she is not valued in her opinion - this is a great way for insecure males to save face when negatively judged by a female.
