I don't think there's a lot of naiveté about the power of fundamentalism and the moderates' fueling of fundamentalist dogma. I just think people are too caught up in the day to give it much attention. Still, purely intellectual approaches to combating it doesn't work. Zealots are content to blow things up, deny human liberty, or attack the judicial branch of government (i.e., the branch of government that protects rights, regardless of what the majority thinks they should be).

Not to come across as cockey, but I'd have to take the fight, physically, to that pastor if he threatened me in a parking lot... Peace!
