I will assume the reason for this post was NOT to point out all men are perverts, but mainly that it's mostly men who are the pedophiles, rapists and murders.
Men generally have a more violent nature than women.
That's not to say women don't behave in "sick" ways, but it is men that conduct the majority of violent crimes.
Men love por*n more than women. Men have a high need for sex. Women are more caring by nature etc......
So why are all men perverts, well it's the way they are wired!
Mary Kay is a very psychologically messed up women. She did not chose a young boy b/c of sexual perversion, she did it for a lack of love or whatever her sick reasons were. If a 40 yr old man were to have sex with a 13 or 14 yr old girl, it's not for love or affection, but for sexual gratification.
Basically, men run on sexual vibes and women on emotional ones!
