Arguments offer insight. Arguments are necessary because not every event presents itself in an ideologically consistent and digestible fashion. Sometimes it is a noble thing to conscientiously refuse to enlist in a war. And other times it is cowardice and treason. The trick is to figure out which is which, and the only way to do that is have people of good will disagree with each other.
Libertarianism is an intellectual acid test for conservatism.
And that is always a good question, even when there's a good answer. But the fact that conservatives are open to the question puts those asking it squarely on the Right. Russell Kirk, who could not define conservatism in a paragraph, much less a sentence, would consider it folly to even try. Rather it is a recognition that life often pits some values against others, and that men are not always brilliant at sorting out which value should trump which in any given situation. I make no pretense that conservatism is always right.
