Most people miss the point
What this story is really about is mob mentality.
The story that springs to mind Shirley Jackson's "The Lottery".
The scapegoat analog the preacher was talking about comes closest to what was really going on here.
It is interesting because you see a very ugly side of human nature-the ganging up of an relatively innocent "victim" against a mob of a million people who decided that this guy was going to be the scapegoat. Just like the poor hapless goat who got tossed over the cliff in the biblical days. If this dude was a 6'5" 285 pound black guy, rest assurred he would not be taking as much crap from everybody. But since many of the frustrated male fans felt they could take him in fight, and they had the "politically correct" backing of the masses, it allowed them to unleash a side of human nature that society rarely allows to be unleashed.
On a very deep level, I remember when this was going down, it was fascinating to watch. On a primitive level there is part of everybody that relishes seeing this poor guy get abused and part that says "Thank God it wasn't me."
People are inherently evil.
