If folks want to influence those not already in their tribe, they would do well to appear objective and examined within their beliefs. I can't tell you how many times I have 'shut off' authors who generously castigate 'the other side' while finding no fault in their own. Boring. Insincere. Biased. Emotions-only with no logical backing. The world, I hope, will belong more and more to those with more honesty.
