Writing for The Freeman, Max Borders lists 30 common fallacies used in “arguments” against libertarian ideas.

Most libertarians find they’re arguing in social media these days. So they’re not only finding new people on whom to test their ideas, they’re finding new fallacies in response. And sometimes these fallacies work, despite being fallacious, which is probably why they’re so commonplace. This is especially true on social media, where one can quickly learn that the real point of these exchanges is to play to the audience, to provide them with an excuse to withdraw into whatever biases they already hold. Still, maybe it’s possible to raise the costs of employing these fallacies—at least a little.

We’ve decided to offer you a fun list of them, which you can use as a handy guide in the process of engaging in well-mannered, reasoned discourse online.

Argument ad KochBrotherium: This fallacy is a cousin to the genetic fallacy and guilt by association. The twist, of course, is that anything that the Koch Brothers ever say, said, fund, funded, might fund, came close to funding, could have funded, will fund, walked by, looked at, support, think about, or mention is invalid by virtue of, well, “Koch Brothers! Boo!”

The Unicorn: You’ll recognize this fallacy from the question, “Why does no libertarian country exist anywhere in the world?” Embedded in the question is the assumption that libertarian countries don’t exist because they are fantastic creatures, like unicorns. Of course, just because something doesn’t exist yet does not mean it can’t exist. Indeed, the Internet in 1990 and the American Republic in 1775 beg to differ. And the unicorn fallacy fundamentally confuses the libertarian worldview with some “L”ibertarian platform that might be the product of some electoral processes—processes most libertarians reject. Michael Lind and E. J. Dionne have brandished this fallacy rather shamelessly, and have had it parried rather effectively by better minds.
