Libertarianism: an idea so good it’s mandatory.

Most libertarians I've met are also nationalists. Especially ones that are anywhere near their local party. They tend to also be pretty extreme nationalists, believing all the war hype unconditionally.

They could be using it in the original sense,where it means a community of people tied together by a common cultural heritage and not in the nation-state sense

Which, don't get me wrong,it's still incredibly racist,as the "white" nation is a fabrication of the American state as opposed to a natural cultural identity
