"Libertarian" in a European tradition, especially in France, was a person regarded to be without any moral. The well-known Marquis de Sade (the term "sadism/sadist" originates from that name) and his "literature" was a typical example by the end of the 18th century.......LOL

Do try to be more careful, Herr Doktor.

Libertaire (libertarian) is not the same as libertin (libertine).
