I think it should also be pointed out that the liberal-conservative axis can be applied to specific issues. This nuance might help to clarify your own positions Penwing. For example, an individual can be liberal on social issues(i.e. Pro-choice, Civil Rights, etc.) but conservative on economic issues (i.e. lower taxes, a balanced budget, etc.).
I think the majority of Americans are probably moderates who drift one way or the other and as such adopt the moniker of either liberal or conservative. As a child and a young teenager I was definately a conservative, but thanks to my damned secular education I have drifted to the left.
