Congress can deem that those born here under a violation of a visa overstay are not entitled to birth right citizenship just like Congress passed laws taking away other rights for breaking the law. Easy
But then a lawsuit is entered & ends up at SCOTUS. I suppose this 5-4 court would likely give it to you however.
True but that would take so many years and there is precedent for denying rights to those who violate a law. A convicted violent felon can be stripped of 2d amendment rights. 1st amendment rights to speech are not absolute. 14th A citizenship can be modified to say you cannot take advantage of the right via illegal means. Could have been done but to say Dems dont want it when GOP had the power to is a falsehood.
