Nice guy vs jerk 

Nice guys often come from a secular background, who are wrongly taught at home from an early age to respect the opposite sex and see her as equal in terms of intelligence and everything else. Jerks on the other hand come from semi-religious households (the extremes of abrahamic religions often) who by default see the opposite sex as inferior and in need of protection.

This makes sense when you think of the so called "Girl-power". Girl-power is completely useless on a jerk, a girl cannot hurt a jerk's feeling with her words and gestures because he's simply not thinking about what she says, but instead if the girl was to attack the jerk physically then he would in fact respond to it very violently. 84.241.20.45  Goshtaasp
