You’re entirely incorrect.
The 14th amendment can be clarified by the Congress, read the Amendment.
That includes clarifying the phrase “..and subject to the jurisdiction of...” in determining the nationality of children born to aliens in the United States.
And there have been at least 4 or 5 such bills introduced over the last 27 years none of which went anywhere.
But could now.
And should. No nation lets illegal aliens pick who their citizenry will be, which is what we are allowing when we tacitly allow their children to pretend they are ours.
Its like arguing that the 1st amendment discussion of religion only applies to congress and not the states. The courts have never seen it that way. Nor have they ever allowed a challenge to the birthright amendment. You can tell me I’m wrong all day but until I see a change somewhere, I have enough sense to know what is going on.
