I disagree with what seems to be your reason for objecting to a man hitting a woman. Sure, men are physically better equipped to handle being hit, but they do have the right to defend themselves against a woman if they're being attacked. A woman holding a knife, for example, should be hit if she's trying to harm someone. I think violence should only be a last resort and men shouldn't hit women for the same reason anyone shouldn't hit anyone. As for the draft, men make better soldiers but women could do many jobs (mostly non-combat) as well as a man. A woman could most likely fly a drone just as well as a man, so she should do that and let the men go out on the front lines.
