Amy Coney Barrett Unraveled the Case Against Birthright Citizenship With One Question

She did so because the solicitor general was so ill prepared.

It’s really good to see justices he appointed not being blind sycophants unlike everyone else in his orbit. I suppose it’s because they can’t be removed by him.

Solicitor General Sauer would try to deny birthright citizenship to people born to people who didn't intend to be permanently domiciled in the United States and people born to people who were still loyal to foreign governments.  What Judge Barrett asked translates roughly to "How do you know what they're thinking?". I will note that ICE has been uprooting domiciles and discouraging people from wanting to be here.  I will note that we had more emigration than immigration last year.  I will note that if birthright citizenship is blocked further than it had been historically, it could theoretically be denied to anyone, at which point America will be without citizens in two generations.  (Read "Starship Troopers" by Robert Heinlein.  Though ICE does deport former US military, which leaves them stateless...)

Pretty sure I could: can you read that sentence of the amendment? Done.
