I've not seen many westerns since I was a child when they seemed to be on endlessly. I wouldn't at all describe myself as much of a fan of the genre.

I didn't mean to imply that I thought slavery was a big motivator for the civil war (EDIT: I simply don't know enough about the war to have an opinion). But I stick by my point that the libertarian position seems to be one in which makes it easier for people to assume that certain other groups of people don't count, or don't need assistance, and their championship of the South (if, indeed, they do champion it) rather reinforces that belief of mine.
