There are quotes there which stand out as text book for anyone who claims to believe in liberty.
"I've never had a puff of marijuana in my life - never had a recreational drug - and [yet] I so want that legal so I'm not paying for enforcement of a law that just seems stupid"
"When I was young and everyone around me was smoking dope, there [were] two things I wanted; one was to never be around someone smoking dope and, two, to have it completely legal."
"I only care about freedoms of things I don't agree with, that's the only ones that test me ... if you have not got the freedom to put what you want in your body, you are not living in a free country"Quite.
Do watch the whole thing as an illustration that we are, indeed, on the side of the angels here. Libertarians like and trust people; prohibitionists don't. It's that simple.
