Wait wait wait wait wait wait, Rayiner. Liberty is a good thing. It does not follow
axiomatically that libertarianism is a good thing. Libertarianism has a quirky and unpopular orthodoxy, one that equates drivers licenses to "a license to make toast in your own damn toaster", and creates utopian New Hampshire townships that are ultimately overrun by bears.
Give me liberty, as the saying goes, but also drivers licenses, and hold the bears.
Libertarianism isn't bad on spec. But it is not reasonable to suggest that people shouldn't be made aware when their sources are all libertarian, as these ones are, for the same reason that it's good to know if your sources are Jacobin, Current Affairs, and In These Times.
