Look, I've heard more than enough about Bohannon from people who've met him to know he's not a guy I'd try to associate with in my personal life. Is he an idiot? Yeah. Does he "deserve" (there's that word again) to die or get permanently messed up? No.
But
@PCHawk nailed it when he said a guy can deserve getting his ass kicked and the guy doing the ass kicking can be wrong at the same time.
At the end of the day its not a big deal. He got obstinate and drunk, and threw drinks on people celebrating a wedding (several people who were there have posted about it in Twitter). Then when he got confronted he whipped the phone out and dared someone to kick his ass, and somebody called his bluff. I would imagine this is probably going to be something that's going to stick with him and embarrass him for a really, really long time which is good. Guys like that need to be knocked down a peg once in a while. Whoever hit him got damn lucky that he didn't hit his head on the corner of a table or have s seizure or something. Not a smart move when you look back on it, but the heat of the moment is a real thing.
Bar fights have been happening for literally hundreds of years, folks. This ain't no big deal. Humble pie is usually good for people and likely the only thing hurt is his pride. Severely.
I mean think about the next time he steps in Hilton and imagine the hilarious signs and memes people are going to make everywhere he goes.
