That's not the way I understand it. I think my views are "libertarian" and here's where I stand: The gov't should not dictate to a private business what to sell or not sell. The decision whether or not to sell any particular pill should be left solely to the owner of the pharmacy, not to the government, customers, or the owner's employees, either.
You are absolutely correct that this is the libertarian position. Don't let yourself be tarnished by a few people who claim to be libertarians but are really part of the hate moralists and love my genitalia" movement.
