Bad Democrat

I’m not sure how the United States would determine who is a citizen if it weren’t for birthright citizenship. If you are born and raised in the US, could your citizenship all of a sudden be up for review due to birthright citizenship ending? What if they chose me? My ancestors came from Russia and Poland in the early 1900s. It would be unprecedented, unclear, and horrifying to revoke my citizenship, not to mention a terrible mistake. Why am I even bringing it up? Because I don’t get it. I don’t know what gives me a leg up over a Hispanic person who was born here.
