WHAT in hell is "drugs-first libertarianism"? I never heard of it before, and I suspect the author made it up to set up a phony straw man to knock libertarianism in general. I happen to know several dozen libertarians and NOT A SINGLE ONE advocates letting murderers or any other criminals off because they use drugs. NOT ONE.
Obviously, you’ve never read a libertarian magazine, and the excuses they make up to defend lowlifes. But save your anger for drug drivers.
