Don’t forget Voltaire, Diderot, Rousseau, and D’Alembert. They were a sordid bunch of actors as well, and also directly led to the same carnage. Heck, even David Hume may have contributed to some of that crap as well with his Empiricist theories that denied anything outside of the immediate five senses.
And quite frankly, the fact that Jefferson supported wholly the Jacobins and their ilk says a lot about HIM, nothing good either (even less so when unlike the other founding fathers who at least had the excuse of slow communication lines for not knowing the true depth of depravity going on during that time when initially supporting it, Jefferson knew FULL WELL what was going on due to being on-site in Paris at the time Bastille Day happened, including the parade of body parts most likely). As far as I’m concerned, Jefferson was as much of a progressive as Roosevelt was. Actually, scratch that, he was even more of one, all while claiming to be for freedom.
All of Thomas Jefferson's many contradictions & enigmas are resolved & explained by the following fact: Jefferson was our original, prototypical Democrat.
He built the mold from which all future Democrats were cast.
