This is primitive behaviour being encouraged by some societies. If you hit someone, expect to be hit back. That's not rocket science! How do you expect anyone to remain 100% calm when you hit them?
This kind of double standards create more violence not less. Little Sissys go out there provoking men because they can't get hit back. Then you have more violence because you encourage them to be less restained. After all, the man will be subdued and taken away to jail if he hits a woman! Bure Kabisa.
