SXSW Bully sucker punch. Justified or cheap?

Sorry, I don't care if you want to fight, or not when you verbally assault my wife.

Something to think about in response to your above statement.

Yeah, and there's an observable difference when you actually are responding to an offense and when you're taunting and bullying. You probably didn't dance and slap at the guy saying stupid stuff: you laid him out directly. What you see from the first guy clearly is different from a guy responding to an affront.
