> The 14th amendment grants Jus Soli. End of story.
But it isn't the end, it then qualifies who gets Jus Soli. And that is the debate.
> The people who drafted the 14th and ratified it were in favor of Jus Soli
Thomas cites Sen. Howard and Sen. Trumbull statements in support of the claim that the 14th amendment ratifiers did not intend to grant universal Jus Solis. Is he a liar?
> ... and Kavanaugh are all hacks for going further back into history than the drafting of the 14th
Kavanaugh doesn't go back further into history, it seems like you didn't read the opinion. He spends very little time on the constitutional question.
> Is he a liar?
Yes, he's quote mining to try and argue that there was some sort of confusion about the implications of the amendment. This was part of the debate about the amendment and whether or not it should be reworded. In other words, Howard and Trumbull were raising the very issues with the text that Thomas wants to take issue with.
That discussion was one which shows that the implications of the text were understood and accepted as a result of debate. It cuts against Thomas's actual argument.
Thomas is a liar. Or at very least a dishonest in his characterization.
