You presume that anyone on the left speaks the truth?
I said libertarians pretend to embrace the free market, furthermore. Those libertarians in politics embrace open borders (a Marxist characteristic; see the second chapter of the Manifesto) and are not averse to progressive taxation.
There’s a difference between libertarian and Libertarian.
I am of the former. The Libertarian party’s foreign policy of open borders is nonsense and one of the reasons they’ll never win a national election.
