Great article and great advice. I hope, and expect that most of the commenters here represent the minority of conservatives.
To me, conservatism is an epistemologically modest view that says we're fallible and we should therefore rely on tradition rather than invention to guide us more often than not. But, it also allows us to change when the evidence of the need to do so is overwhelming and persistent. Remember until recently (say around the time of Carter/Reagan) the philosophical viewpoint most associated with Americanism was neither conservative nor liberal, but pragmatic.
We need to be pragmatic, but skeptical as we move forward.
