I would hit a woman, too, if she tried to hit me. More like slap, but I would definitely fight back. I'm all for equality. Women want to be equal? Okay! What is this frail damsel shit? But I wouldn't go as far as that dude in the video, that's ridiculous and psychopathic.
That said, that dude sounds like an embittered individual who needs to take his misogyny out on women due to his past history with women.
