Should men be able to hit back against women?

I'm all about fairness. But the strength between man and woman IS different. There are women who probably stronger, but most men are much stronger. So if a man got hit by a woman one time and you've tried to talk sense into that woman but she just would not listened and keep punching, then maybe you can hit back, THOUGH, please don't go full power. But the first suggestion I would give to anyone, do not be the one who start the punching.
