"Values shouldn't be easy things to hold, and if we can't hold onto ours when they come into conflict with others, then we ought to let them go. But we can't maintain any meaningful sense in the phrase "I believe x to be true" if we also allow not-x to be equally true. Not to get all law-of-noncontradiction on you or anything, but rules are rules. I prefer interlocutors with whom I totally and completely disagree, but who will own the passion of their convictions and translate those into discourse and action, over interlocutors who don't want to disturb the peace of parlor conversation."
