It can be said, with some justice, that libertarians apply only one measure to every issue. But what a sublime yardstick it is. Libertarians ask, about each thing they encounter in public life, “Does this promote the liberty, responsibility, and dignity of the individual?” Libertarianism can have political implications, but politics is, by definition, mass action. And libertarians don’t believe in the masses. They believe in the individuals huddled in those masses. A pure libertarian is opposed to politics down to the soles of his shoes (or, libertarians being libertarians, down to the bottom of his sandals worn with socks). Libertarianism is contra-political, an emetic dose to be given to politics.

From the other side, Progressivism and the authoritarian impulse. About that, McQuain comments:
This is the real problem we face in America. Jeff G. calls it “un-American”. In the strictest sense of the word and given the fact that it rejects everything our founders believed in – I agree.
