Over words. He punched her in the face and you are fine with that. Over words. Ok.
He tried to shake her off so she would let go of his arm
She grabbed a blind man and interfered with his being led from the crowd by his wife
She feel back on her own oxygen tank
He can't see to sucker punch her
If you are blind and someone grabs you, you going to let them attack you? Or would you try to shake them off? If you are disabled and being led by you family member, wouldn't you try to get back to that person or let yourself be attacked?
He didn't grab the woman, she grabbed him. Man, women, old, young, does not matter. He was the one attacked first. He tried to get her to let go of him.
If she fell or tripped and landed on her tank, he did not attack
She had no reason to walk up behind him and grab him.
