Alright, let me preface all this by saying that I believe no respectable person would lose their cool like this and, if you did, it should haunt your conscience pretty much forever. And regardless of society's shifting stance on the matter (and whether it's right or wrong), I personally treat women different than men in many circumstances. But for the sake of playing Devil's Advocate and holding a mirror up to our words, I'll say:
Easy with the hyperbole. It [shouldn't be] so black-and-white in today's world. What he said is in line with what many women's rights activists would say.
I noticed the phrase you elected to use here. Is that truly how broadly it should be applied? So if it were a let's say 5'6" 150 lb guy who took the first swing at this, I don't know, 6'0" 200 lb guy, the bigger guy should still just take it on the chin? Also curious - what if this kid was raised in a home where his father beat his mother? That doesn't mean that hitting is suddenly the right way to solve arguments, but it could mean that it's the only way he's ever seen it done. So is he crazy and worthless then, or does it mean he needs better mentoring? Again, mentoring shouldn't necessarily mean a full ride scholarship, but maybe the time and effort put into punishing him should be appropriate but minimal and the time and effort put into making him better should be great.
there is a comedian I like who actually addresses this specific statement. He says, "so let's say your wife is drowning your three kids when you get home. She's already got one and two when you get there and she's starting on number three. Could you give her a little smack then?" Dark, I know, but the point, again, is that it's not so black-and-white as we commonly make it seem on social media. And yeah, I am astounded that this occurrence didn'the result in a posse being formed, considering it happened in Oklahoma.
I hope life brings him the punishment he deserves (but he also learns to be a better person) and I hope she quickly finds peace and a happy life. Again, I just wanted to point out that we watched sixty seconds of video, deemed him "evil", her "innocent", and silently agreed to chastise anyone who spoke a remotely different narrative. That is a sillily simplistic approach to an incredibly complex world. Just my two (or so) cents.
