It's not the exact same but the point is there for you to see when you decide to stop being so offended over people arguing that what Coleman did was wrong.
Just because someone asks a favor, that does not give you the right to do what was not asked and ruin that person's property. Don't act as though Coleman did not know what he was doing. He was dressed as Colston and someone handed him a Colston jersey to sign. Are you seriously going to argue that Coleman should not have known that the fan handed the jersey to him with the permission that he would be getting Colston's authentic signature on it? If it were just generic items like footballs and such, then it wouldn't have been such a big deal. But to put your signature on another player's jersey knowing that wasn't what the fan wanted?
It astounds me that some people are so incapable of realizing why the fan was upset.
