It’s important to distinguish between positions of the Libertarian Party, and those of the diverse range of libertarians.
Just as we might say that the Republican Party “believes” XYZ, while conservatives might disagree (sometimes even among themselves)
Nonsense, their party perfectly represents libertarianism, that is why they formed it, to put their philosophy into the real world of political positioning.
The tiny liber party is a pure representation of libertarianism.
