The continuum is from right to left.
A conservative is conservative on economics, national defense and social issues, a libertarian accepts the economics and then starts listing how far left he is.
Bingo!
This one dimensional number line metaphor does nothing but cloud thinking. It is a crutch so people don’t hurt their brains thinking too hard.
I see it as two dimensional, with traditional Lib vs Conservative on the X axis, but Statist/Libertarian on the Y.
That would place Randian Objectivists in the upper right quadrant, Hippie Libertarians in the upper left, Communists in the lower left quadrant and Fascists in the lower right.
One benefit of this construct is that when Libs trot out the claim that Obamacare is a center-right, market-based solution, you can easily back them into an admission that it’s Fascist economics...
