Thank you, roamer! I was thinking the same thing.
I winced when talked about "libertarian metaphysical anemia", but kept reading. But when he trashed Ron Paul as "a third party crank", that's where he lost me.
Especially since the author's complaint about libertarians is precisely that they are not so anemic as to roll over and sell out those liberties (those related to separation of state and society) that the author considers dispensible.
