I have no problem with the sucker punch. The bully got what he deserved, with the punch and the following arrest.
With that being said....last year I was at a Saints game, with my wife smoking a cigarette in the little outside section at the Dome. Some guy, a local fan nonetheless, told my wife he wanted to have sex with her, then told her he wanted her to bend over and hit it from the backside. My wife freaked out, and told him he was a drunk fool. I overheard the whole conversation, walked-up to the dude, and told him what he said was offensive. He then told me he wanted for me to watch him do the aforementioned acts to my wife.
Well, I pushed him away from my wife, and he yelled at me that he didn't want to fight, yet laughed at my wife saying he still wanted to have sex with her. I punched him, square in the face, putting him on the ground. Sorry, I don't care if you want to fight, or not when you verballly assault my wife.
Something to think about in response to your above statement.
