Discussion is healthy. I always try to remind myself that other people may have very different views on a subject than I do, and I try to understand how they got there. Sometimes I wind up changing my mind.
I think the biggest problem in politics (and not just in US politics, local, state or national, but all over the world) is that when someone takes an absolutist position they won't alter it, even in the face of facts. Questioning these views (even calmly, gently and rationally) is taken as a personal attack.
Churchill got it right when he said that democracy is the worst form of government - except for all the others.
