"Left" and "Right" shouldn't be subjective. The Left has been liberal and the Right has been conservative since 1789. The problems of definition come from muddy thinking and misapplication. It's tricky to say that the right is "anti-feminist" when the right predates suffrage. It's trickier to say that feminism is leftist when the earliest feminists were also closely tied with prohibition. HOWEVER it's easy to say that requiring parental or partner consent for abortion is a conservative idea and anti-feminist. Case in point: no one on the planet would argue that Libertarians are leftist. On the political spectrum, Libertarians are so right-wing that they loop back to appear somewhat like anarchists.
Libertarians in the sense of the third party that had Ron Paul as a front runner? I absolutely agree. Libertarian as a second axis of the political spectrum (libertarian/authoritarian as well as liberal/conservative)? Not at all. That second meaning of libertarian, defined by its contrast with authoritarian ideals, can be liberal or conservative.
