No I wouldn't.
I learnt the hard way though, I used to work in a restaurant, husband and wife are arguing, he leans across and slaps her, I go up all guns blazing (was about 18 and 5'2" and about 7st) tell him to get out, the wife turns on me, how dare you embarress my husband, who do you think you are, he sat there smirking.
They finished their meal and he started on her outside the restaurant....saying you just wait til we get home you made a scene etc etc.
Anecdotal yes, but makes me think of the repercussions for the woman.
