A man hitting a woman is much worse than vise versa

Men and women are physically built different. A woman slapping a man with all her force will most likely not harm him but if he did the same she could be hospitalized. I believe a man should never hit a woman unless it's a life death situation and hitting her is the only way out. As for self defense theres other ways to protect yourself like blocking or holding or removing yourself from the situation instead of hitting her back.
