It depends on the circumstance, this woman was complete out of control.Slapping women is very suss and un-manely, only a niggas lay hand on women and not real men, I would get involved if I such thing around me walahi.
Anyway, when it comes to gender equality, I believe we are both equals but for many reasons women are smarter then men are superior than, for example men do most of the dumbest crimes and risk their life's for a long imprisonment for something stupid and unnecessary, women are much more mature, carefull, predictable unlike men.
