@richardmurrayin answer to your question asking why I think anyone born in America is automatically a citizen, I tend to think in the abstract when it comes to land ownership, maps, boundaries,territories,etc.
The Earth is ground under our feet and doesn't belong to anybody! All claims to it, like treaties and deeds are man made agreements; just pieces of paper.
So, technically, wherever you were born, is your birthplace and that qualifies you to claim citizenship in the place where you came to life. It's that simple to me. All the rest is superficial.
I neither love nor hate my birthplace. It is what it is. and I take that in my stride.
