On the topic of libertarianism..
Almost all statists share some libertarian perspective on some issues. No libertarian has statist perspective on any issues. There are a lot of self proclaimed libertarians, Christians, Muslims, or people of any principle, who are incorrect. Unlike "Republican" and "Democratic" which don't mean anything, "libertarian" means something. You can claim you are "libertarian" just like you can claim you're a "martian", but it doesn't make it so.
Joe Rogan and Adam Carolla are not the only two who mistakenly call themselves "libertarian" at times. They just don't know what it means.
"A libertarian is a person who believes that no one has the right, under any circumstances, to initiate force against another human being for any reason whatever; nor will a libertarian advocate the initiation of force, or delegate it to anyone else.
Those who act consistently with this principle are libertarians, whether they realize it or not. Those who fail to act consistently with it are not libertarians, regardless of what they may claim." — L. Neil Smith
