IMO there isn’t much to discuss about. Hit me, I hit you back. I don’t understand why I have an obligation to take care of an aggressor who hit me first. I’m not saying immediately kill the other person but it should be at least equal to what I had to take.
It doesn’t matter if it’s a man, woman or even another species.
One exception: The person has obvious reasons reasons like alcohol or substance abuse and is not able to think clearly what he/she is doing.
My parents teached me to not hit people in the first place. This is also a very good strategy to not get hit 😉
