Mises.org

The Ludwig von Mises Institute (aka mises.org) is a major online repository of libertarian articles, lectures, and other assorted word-vomit. Co-founded by Murray Rothbard and Lew Rockwell, and named after Austrian economist Ludwig von Mises, it's become something of a Mecca for libertarian thought. If you're arguing with a libertarian on the internet, being hit with a barrage of mises.org links is a question of when, not if.

Mises Diving
Due to the huge number of articles on the site, and the libertarian tendency to try to tie everything to their ideology, you can find some libertarian opinions on almost any topic with a simple google search. Poor understandings of the French Revolution? Got you covered. Bircher conspiracy theories about fluoride? Of course. Desperate attempts to tie into pop culture? Naturally. In fact, it's somewhat of a running game to see who can find the most preposterous hot take on the site. Many of the quotes featured on this very wiki are the results of those electronic dumpster-dives.
