I agree that hell is the ultimate trump card pulled out when they want you to go along with political agendas and such, but not all religions believe in hell - certainly not all people believe in hell.  So the problem is that we allow politicians to spout the garbage oppose to giving us sound and reasonable cause for actions, laws and such - we vote them in - we can vote them out.  But we as a whole have decided to continue to vote the same morons in on both sides.
