If you ever shook your head at theocratic regimes such as Iran, well maybe look a little closer to home. "But... the people in charge of Iran are hypocrites, they do nasty stuff at home behind closed doors."

Mark my word, if and when these preachers get control of the [Republican] party, and they're sure trying to do so, it's going to be a terrible damn problem. Frankly, these people frighten me. Politics and governing demand compromise. But these Christians believe they are acting in the name of God, so they can't and won't compromise. I know, I've tried to deal with them.
