So who had a hold of her hair when she retaliated? Did you observe that?
If you think it's right for a 6'1, 200 lb. 19 year old punk who had no business being in a bar, to punch out a female then you need to get your own ass kicked just for your apparent stupidity.........
I don't know what planet you came from bro but you don't belong on ours........sheesh!
He had ahold of her wrist (and hair, because it got tangled up) because she’d already presented her fist as threat and made a move to punch. It was a defensive measure on his part. She initiated violence not once, but twice before being punched.
