Your pie maker is a huge fan of Information Dissemination precisely because its lead author writes columns like this about The Great Green Fleet. There is no doubt what his opinion is, but it is always presented in a way that acknowledges the humanity and likely good will of those with whom he disagrees. This is the heart of how to disagree peacefully and present opinions that one holds based on consideration of observations, rather than as a fundamental part of one's identity.
Consider, for contrast, the Conservative and Occupy movements. In the recent GOP primaries, affirmation of Conservative credentials played as large a role in the discussion as any policy provision, with the assumption that present Conservative orthodoxy can and ought to be applied to all past positions. Even staffers at the Supreme Court feel that they ought to attack those who break ranks, threatening the Court's legitimacy to affirm their identity. The demands of Occupiers for jobs and social justice are perhaps noble, but the movement, much like the Conservatives they oppose, proclaim more of an identity (we are the 99%) than a coherent message.*
This leads to a poisonous environment for debate because it suggests that all compromise is a failure to uphold one's values, and thus a surrender of one's identity. How do we produce more Gahlrans, more people who are confident enough of their own intelligence and good will to acknowledge it in others? Your pie maker believes the recipe calls for equal parts of humility and affirmation from sources such as this column. Humility because we are all limited, unable to fully understand our own interests much of the time, much less something as complicated as the modern economy. Affirmation because it encourages engagement, creates comfort and allows us to face the often painful cognitive dissonance that's necessary to correct a mistake.
*"Lower taxes" is a consistent theme for Conservatives, and "more taxes for the rich" for Occupiers, but the consensus tends to end around there.
