Punk hitting the fan isn't that big of a deal. I think people are massively over reacting. He was surrounded with no security and swung after getting hit. He didn't go out of his way to beat up one fan in particular for no reason. It isn't Ron Artest thinking he's Godzilla in the crowd.
If the guy sues he'll get some money, not millions of dollars. If he's actually a wrestling fan, he'll probably get way more out of it not to sue. It won't stop Punk's push, won't change the company, won't do anything. It's just not that big of a deal. The number one rule in wrestling is you don't touch the talent. Even if they cross the barrier. There is no way that everyone in the back doesn't fully support him on this one, even if he did hit the wrong guy.
EDIT: Regarding King Mo, I can easily handle the ridiculous outfits and robes and what not. That's pretty pro wrestling. But I couldn't take him seriously when he came out as this big bad ass, but looked like Titus O'Neil lost 4 or 5 inches of height. He is shorter than James Storm and Bobby ROOOOOOOOooooo.
