Just a quickie; The fantastic libertarian magician and juggler Penn Jillette describes it as “as far to the right as you can go on money, and as far to the left as you can go on sex”. I love that description, but I’ve come to use this phrase to describe libertarianism as I see it (in a way the ‘old guard’ could contextualise it):
Fiscally competent and socially tolerant.
I dunno. That’s what I’m finding myself using more often anyway. By that definition, the left are socially tolerant but fiscally incompetent, and the right are fiscally responsible (sometimes) but socially intolerant.
Libertarianism. Reaches the parts other socio-political theories just can’t. (!)
