Most of Jones' opinions seem to revolve around the idea that cabals of conspirators are trying to trick people into accepting exploitation or tyranny. I don't keep up with all his different ideas, though.
It seems like you dislike this idea, and are just associating with Jones who you also dislike. I don't see how you get from his conspiracy worldview to my opinion that an archaic social institution might be worth another look. I don't see duelling as incompatible with having a functional legal system.
What does this opinion of mine have to do with Alex Jones? If you're suggesting that all unusual ideas are somehow adjacent to each other, I don't think much of your categorical skills.
It's worth digging into this stuff, because it's kind of fascinating. It's a reason to go look up what the largest fortunes were at the time of the founders, or what the major defamation cases where at the turn of the 19th century, or how defamation law differs now from the time of the framers (hint: it got a lot more favorable to defendants).
If you use dumb-seeming arguments as an excuse to speed-research weird historical facts, these threads get a lot more fun, and also you tend to end up with more compelling arguments.
None of that is relevant here, because defamation is an established exception to the 1st amendment, totally separate from incitement of lawless action.
