Joe Rogan is an American commenting almost exclusively in the American political context. Referring to him as a liberal in this context is misleading, as the term here is almost exclusively understood to mean “center-left relative to American politics” and is almost never used in the economic or philosophical sense in mainstream political commentary.
I'm aware of who he is, and the context of "liberal" when referring to him and his views. I'm offering an explanation as to why someone might describe him as "liberal", because if anyone outside the US listened to his viewpoints they would describe him as "liberal". I'd be willing to bet that the original commenter is not American, and that's why they chose "liberal", not to be misleading, but because literally the entire rest of the world uses the word differently.
"USA: the primary use of the term liberal is at some variance with European and worldwide usage. In the United States today, it is most associated with the definition of modern liberalism, which is a combination of social liberalism, public welfare and a mixed economy,[12] which is in contrast to classical liberalism."
> because literally the entire rest of the world uses the word differently
This assumed cultural hegemony by some US citizens is frustrating as hell; they are incredibly quick to assume (or demand even) the rest of the world knows their cultural references/idioms/etc., yet make zero effort to discover what the rest of the world is doing. Unfortunately they are also loud and so it's easy to come to the false conclusion all US citizens are like that.
I'm a Brit, I would no think of Joe as a liberal, and I only read this thread as I was so shocked to hear he might be a left leaning commentator. Obviously reading this, he is not.
I'm also a Brit, and to be honest, the term "liberal" in a political context has lost all meaning for me since everyone seems to have their own definition of what it actually entails.
