John Hagee is a pompous rotund fuzz ball whose sermons consist of one liners planned to receive applause. He was on the board at Oral Roberts University which mismanaged the school and got it $50 million in debt.
Hagee says Jerusalem belongs to the Jews, and the Jews already have a valid path to redemption and need not convert.
You really can't hold Hagee's beliefs regarding Jews and not run into trouble with Rome.
