completely agree. slapping someone is an invitation to get punched in the face and/or shoved down (both of which carry a serious risk of death or coma due to head trauma), regardless of if you're a woman or not.
this is the real world, not movies. many people (especially men) and animals retaliate automatically when attacked physically. it doesn't matter what gender the attacker is, there's a high chance you will get your ass beat if you assault a man, regardless of the context.
