I think the “Libertarian purity test” might possibly be a little starved for attention.
Out of 160 points, I scored a whopping 39. And according to the test results, my "libertarian credentials are obvious. Doubtlessly you will become more extreme as time goes on".
Oooo-kay. I'll just file this test score alongside my socialist party membership card, so my "libertarian credentials" can be be exposed to the harsh light of socialist reason.
