An interesting quality.
They seem to protest only those things which affect them directly, and the hell with the rest of the world.
A so-called Libertarian supporting a war to take away another countries resources is a contradiction, and yet there they are. And a Libertarian supporting a dictatorship seems to be another contradiction, yet there they are.
Libertarians (so-called) seem to have no insight into their own contradictions and no empathy for anyone else or their rights.
I admire parts of what they can believe, truly do, and have read a book, "How I Found Freedom in an Unfree World" which is superb. In practice, however, it seems Libertarians are the essence of greed and selfishness.
