People like Peter Thiel are #libertarian in the sense that they want the liberty to do whatever they want to you without censure or consequence.
In french we have two separate words wich clarifies a bit:
* "Libertaire" is near the same thing as anarchist. No doubt that it is a revolutionary leftist.
* "Libertarien" is basically the liberal trend of a part of the far-right. No doubt that it is a "raclure de fond de chiottes de l'humanité".
Off course, we also have a few clowns who label themselves as "ancaps" but it realy is right libertarian with a mustach.
Yes, in the US, the ancap Murray Rothbard bragged about having stolen the term “libertarian” from the left and co-opted it for his own purposes.
