Exactly. And they could just as easily have required people to stand on one leg every third Tuesday if they wanted to keep their citizenship. The point, about which you are being deliberately obtuse is that if citizenship is granted by the whim of congress, it isn't natural.
Prior to 1922, people born in foreign countries to one citizen parent were NOT CITIZENS AT ALL.
Now you guys are coming along and trying to argue that they are the same as "natural" citizens. I would say you are lying to yourselves, but I don't even think YOU believe this bullSh*t.
Speaking truth to power here.
