There is no one alive today who was “mass naturalized” by the 14th Amendment.
I realize that you find great fault with this but over the last 145 years since 1868, Article II, Section 1 natural-born citizens and 14th Amendment Citizens of the United States at Birth have merged in the minds of a majority of Americans including judges and members of Congress.
And this is exactly correct, and descriptive of the Problem. It is the false conflation of the Wong Kim Ark ruling with "natural", coupled with endless repetition of this false application of precedent, with numerous inputs from other erroneous sources, about an issue that has only come up four times in the last 200 years. (Arthur, Hughes, (George)Romney, and Obama.)
The Vast Majority of the Public has a simplistic understanding of this subject, and most have no interest in understanding it more accurately. Even those people who's job it is to get this right, simply don't care if they get it wrong, or more accurately, will not even entertain the notion that they could possibly have gotten it wrong.
They are "Certain" with so little reason to be certain.
