So, how quickly and accurately does one have to size up their opponent before they get a pass on self-defense? If your opponents first blow falls short, do you have to wait for a second to see if they are actually capable of landing a punch? If he had only been one and a quarter her physical strength can he slap her? If their strength was roughly equal could he have hit her as hard as physically possible? At three times the physical strength does he have to politely ask for another blow? Do you realize how ridiculous applying this self-defense matrix is when you suddenly find yourself in a violent confrontation with someone you know nothing about? The human brain simply does not work that way.

The physical differences between a man and a woman will almost always make this an irrelevant comparison. If a woman wants to stop a man doing something she doesn't want him to with force, she almost always has to use as much force as she's physically able to (unless she's trained or very strong, obv), a man in the same position has a bunch of other options.
Sure, the situation could have unfolded in a thousand different ways. That doesn't mean that he was wrong to defend himself when faced with what still looks like unprovoked aggression. In a perfect world should he have shrugged it off and walked away? Absolutely. Does defending himself from an out-of-control woman make him a criminal? I don't think so.
