Surely we’re aware of the Heritage Foundation’s Project 2025 yes? It spells out exactly what they are doing, & where they are going.

Eliminating birthright citizenship is a key component dating back decades.

Thanks for posting that link. I read part of it and their reasoning strikes me as contortionist. Good then that after decades, as you point out, that argument has not won out.

I would love to actually debate this issue with someone who does believe birthright citizenship is not a thing.
