The way you get a huge congregation is by entertaining them. Go to any mega-church and you will see this. The preachers are always saying wacky stuff. It's what brings them out.
In my university I have heard all sorts of nonsense from preachers. Being as I was required to attend, I did not protest the silly things they said, because I liked getting paid, and basically, what they said was harmless. There was never a call to any action more extreme than putting money in a plate. Being as for every one of the 32 years I taught there I believed that the Bible was not the word of God, I disagreed with pretty much all they said.
What Wright said was also harmless. So far, no extreme actions have been inspired by him. Hes just a wacky preacher blowing off steam and entertaining the masses. Sort of a religious George Carlin. A less musical MIck Jagger.
