Judging from some email, I should clarify: I do not think Cato is a loony bin or anything of the sort. Some jokes of mine notwithstanding, I’ve always thought Cato does serious work and has lots of serious people. And, I should note, one of my best friends is Ron Bailey, the science correspondent for Reason (I will deny this if it gets him in trouble). My point is that these bastions of libertarian authority are quick to denounce and criticize liberals and conservatives but too often seem to have an 11th Commandment — assuming for the moment they subscribe to Commandments 1 thru 10 — which says “thou shalt not criticize any other libertarian.” I think that’s not only irresponsible, it undermines the oft cited libertaran assertion that they are an independent and intellectually consistent political movement.
