Since when do guys (generally) treat girls differently?

[Anonymous]

I'm ashamed of what I'm about to admit:

In my school years (all the way till 9th grade) I've annoyed some guys. It included stepping on his foot, nearly tripping him by sticking my foot on purpose, grabbing his bottom and throwing water on his desk and shirt. Some didn't care and a couple of them had a ''not this again'' looks and one actually complained to my mother and a teacher.

In comparison, my younger brother already has gotten into a couple fights but much less. During an argument, he insulted another guy's mother and it immediately led to a fight. Neither of them won. It was even.

Perhaps I'm older already (26 years old) and it was a slightly different time. But since when do guys (generally) treat us differently? All of the above I did would've been enough to start a fight or get strike.

I'm also guilty of doing what my brother did (during an argument tell a jerk in anger ''I would pee on your stupid mother's grave'') and he left, kicking the an empty soda can saying on the ground, saying ''biotch'' over and over again.

Most guys will not hit a woman even in self defense. The best case to treat differently is life or death scenario. Ok story time. Met this dude at the bar. Cool dude but short fused. He had definitely seen his share of fights so imagine my shock when I found out his girlfriend/baby momma who lied cut him. He didn't lay finger on her. He went drove himself to the hospital to have like 10 stitches in his forehead. He is in jail now for a bar fight with another dude. Nearly killed the other guy. Don't ask for it.

I know I would never hit a women unless my life depended on it or she attacking my mother/sister but thats something that would almost never happen. One my friends mom got attacked by a hooker once, he didn’t hesitate ko her on the spot. We got sweet spots for our mother’s and sisters.
