Celebrating leading up to the Super Bowl? He was perfectly happy to rub it In everyone's faces when it was going well. But when it doesn't go his way he sulks and acts like a child.

Manning refusing to shake hands was classless. And those making excuses otherwise should be called out. But Manning often carries himself as a professional, while Newton's attitude seems to rub people the wrong way. I think that contrast may be a reason for the contrast in response.

I hate it when we try to simplify everything down to race. Is that a contributing factor for some people? Probably. But there are other reasons for the reaction that have nothing to do with race. And those get ignored because everyone is so excited to catch people being racists.
