Some of the Founding Fathers were more easy-going than others, of course, but when it comes to easygoingness, Jefferson was at the top. But he sounds considerably more restrictionist than Trump when he talks about immigrants from absolute monarchies, for example, in Notes on the State of Virginia [link]:
"They will bring with them the principles of the governments they leave, imbibed in their early youth; or, if able to throw them off, it will be in exchange for an unbounded licentiousness, passing, as is usual, from one extreme to another. It would be a miracle were they to stop precisely at the point of temperate liberty. These principles, with their language, they will transmit to their children. In pro- portion to their numbers, they will share with us the legislation. They will infuse into it their spirit, warp and bias its directions, and render it a heterogeneous, incoherent, distracted mass." - Thomas Jefferson
Something to think about the next time some SJW tells you not to worry about immigrants, that they'll assimilate right away. You do realize, do you not, that every damn one of the Founding Fathers would be voting for Trump right now, don't you? More on the subject here [link].
Quibcag: And he said that awful bigoted stuff in the quibcag, too. It's illustrated by a girl who looks like Kato Marika of Bodacious Space Pirates (モーレツ宇宙海賊パイレーツ Mōretsu Pairētsu), but evidently isn't. I chose her because her outfit — well, 3.4 of her outfit, are rather similar to what Jefferson and his buddies went around in back then.
