One quick final comment about the labels "liberal" and "conservative": they are useless. Utterly worthless. They really say nothing about the one being labeled except he/she is to the right/left of the one labeling. In other words, all they do is point out that the labeler believes that the one being labeled "conservative" seems to be to the "right" of the labeler, or that the one being labeled "liberal" is to the "left" of the labeler. They say more about the labeler than the labeled.
And as pointed out above, the labels can be very misleading, and since they are typically used polemically, their function is mostly to stir up prejudice rather than to clarify arguments or positions.
Here's why I added this note: I've asserted my conservatism before, and some of my politically "conservative" friends have ignored it and simply responded by saying that they see nothing "conservative" in my positions. Go figure. Of course, I don't care. I really don't. I don't care where I fall on the political spectrum, or whether I'm to someone else's "right" or "left." It's meaningless. Why? Because I'm a Christian. That is my one allegiance -- both in my life and in my political, moral or philosophical arguments (not to mention theological!).
So, when politicians tout their "conservative credentials," I just have to laugh. It's nothing more than a marketing ploy -- an emotional appeal that they hope will garner support from people who actually vote. It's philosophically untenable and in fact dead wrong if one cares to examine the claim.
