People, wake up! Extremists ultimate goal is the control of what one thinks, talks and does. No matter if that extremist organisation is a political or a religious movement.
The worst case of religious extremisms is the iranian dictatorship under the mantle of religion. I am pretty sure, that most Americans do not want to go there. Preaching God's way and at the same time shutting humans out, because they break their moral codes, is the first step of dictatorship.
Democracy means accepting many opinions and ways of living. Shouldn't religion do the same?
