Truth, honesty, balance, no double standards, and not sweeping problems under the rug of obscurity are what helps prevent extremism. Usually a swing to the right is provoked by a prior swing to the left. those in the middle, without allegiance, usually make the swing.

The way to prevent extremism is to engage, not ignore or obfuscate, the concerns of those in motion.
