Meanwhile, here's a Wiki with something like 2,000 pages trashing libertarianism. It's obviously a huge labor of love. The list of quotations on the front page is worth it all alone. Here's a good one:
So much for the idea that so-called libertarians are uncompromising champions of freedom. In truth, they're tireless defenders of the idea that the people with the most wealth and power in our society deserve to keep it. This, of course, is hardly the subversive, counter-cultural brew that libertarians seem to think they're peddling--this is exactly what bought-off establishment politicians in Washington already think.
Tyler Zimmer, "Gary Johnson and the libertarian swindle"
Libertarianism is obviously ridiculous bunk. It hardly seems worth arguing with, it's so stupid. But it has a tenacious hold on many a washed brain, because there are powerful interests -- e.g. the Koch brothers -- who invest heavily in making it seem like a coherent, intellectually respectable philosophy. Anyway, enjoy exploring.
