SXSW Bully sucker punch. Justified or cheap?

I guess bullying is okay with you? I don't know how it'll stand legally, but personally, I think the guy got what he deserved.
no, bullying is not ok. To me, this guy didn't act like a bully. He acted like a mad(obviously-a stronger word should go here) person, so who made him mad? The two that might have started it, and then decided not to fight. We just do not have the answers. But either way, it was not this guys business.
