If women want the old rules of a man should never hit a woman to still apply, then a woman should never engage in physical violence towards a man(ask any old woman and she will agree she was a tit for taking it that far)... why put yourself in that situation in the first place? Hitting someone and saying "No no you can't hit me, it's not allowed see!" sound like a defensible stance to hold for anyone?
I haven't seen the vid but I think women have changed, some women are far bolder with advances in sports science and fitness programs in general a lot of women can look after themselves better these days, you only need to look at UFC crowd fights and you will see the extreme examples of the sort of women who will pick a fight with a guy and leave him with a unfair choice to make.
