Good question. Not sure if you're being rhetorical or not, but I'll respond as if you're not.
I think a lot of people secretly (or perhaps not so secretly) wished someone would have lit her the fuck up.
Now, had a guy done just that, I'm sure there would be some that would applaud it. However, I'd think that there'd also be people who would say something like, "He went too far," "Men should never hit women," etc.
Think here the McDonald's video of the chick getting McJacked by the male employee. She (probably) deserved it, but still there were some who said he took it too far. Same thing would likely happen here: Evolution Edith here deserved to get knocked out, but if she had been there would have been those sympathetic toward her.
Just my thinking.
