I don't know... it seems "conservatives" really don't follow one particular line of thinking. Many self-titled "conservatives" on FR and other forums disagree with each other on major issues. I myself do not identify as "conservative", even though I vote GOP (though I've also voted LP) and agree with "conservatives" on most issues.
That is not my experience. Many times when you scratch a self-titled conservative you find someone who is really not a conservative at all. Being a conservative on 2 or 3 issues is not sufficient. Going by my circle of friends, all conservatives, we agree on what I call the bedrock issues. By and large, any "disagreements" are on fringe issues and, even then, on the margin.
