Well surely if an American citizen believes in their constitution, then the idea of inalienable rights must extend to all human beings. If they're inalienable then there really can't be an argument against those rights unless you want to appear to be living by a double standard.

Just because your government guarantees them to your citizens surely doesn't mean that other non US citizens don't have them.

I think the issue is that if the people of the US live under the assumption or idea of inalienable rights, then surely anyone who has any dealings with the US regardless of the nature of those dealings, must be assumed to have those very same rights simply because they are inalienable. They're natural or 'God given' if that's your preferred wording.
