to me, it seems as though all issues have a binary number of stances one can take on, that is, those which follow the harsh realities of nature (competition, hierarchy, darwinism), and those which believe they can ascend their biological substrates(socialism, most other things on the left).
This is what leads me to believe politics isn't a spectrum, but more of a dividing line, and yes, under this classification, libertarianism is a right wing ideology.
