Will Wilkinson defends himself and his brand of libertarianism from Dan Foster, and all I can say is read the whole thing. Here is one quote to pique your interest:
Foster’s worry about my sort of libertarianism isn’t really that it’s a “rationalist” ivory tower abstraction remote from the lived experience of the allegedly natively libertarianish American tradition. It’s that the application of any rational scrutiny (libertarian or not) to the efforts of conservative elites to construct bullshit American-heritage narratives tends to get in the way of elite conservative political aspirations.
It reads like Will’s being walking around for years waiting for someone to make just this attack on him; the kind of thing he wrote in 10 minutes because he’s written in his head 100 times already.
