Things used to be wild. You think women have it tough now? It's way better than it used to be. Even as recently as the 80s it was perfectly acceptable to slap a woman in the face in public. People would see it happen and just figure, "she must have done something to deserve it." It was a different time. I say let's bring that back, but it should be true for both parties. You're allowed one slap per day. If you exceed one slap, then you get arrested. I think that sounds like a great law.
Things were so wild in the past that women had to resort to walking around with boxing gloves for protection. At least... that's what I'm guessing. You'd think a knife would be the better option but then she might kill her attacker, which would get her in worse trouble. Like I said, being woman wasn't easy.
