> Such people rarely change their beliefs.
You honestly believe that 50% of the country rarely change their beliefs? That we are actually divided into the "rational good people" and the "religiously fevered bad people"?
Most people that voted for "the other side" did so because they thought it would be better for their jobs, better for their taxes, voted the same as the rest of their family, were misinformed, or a million other reasons that has nothing to do with them being unshakable ideologues incapable of being convinced otherwise in the next election and not deserving of your contact. The fact that you view half the population of this country that way is quite frightening.
