You think people like this exist only in sitcoms?
Hat Tip to commenter Scott at Sadly, No! where they discuss a similar mindset among the wingnuts.
Another classic quote from commenter Robert M.:
I think that most Americans have a deep-seated need to believe that if they really, really had to–if a hellish post-civilized world came to pass, and they were forced to pick up a knife/gun/katana/etc.–that they would become total badasses.
If you look at glibertaranism through that lens, it makes a lot more sense.
