How is the child a ‘citizen’ of another country. She is an American, not a Mexican. That’s the whole point of birthright citizenship.
Her parents are Mexican, but she is not.
I agree, don’t confer citizenship on the parents, but the child is a whole different matter.
If you let the state decide who is and who isn’t a citizen, based on who their parents are, this is contrary to gaging people on their own merits.
I guess then hyphenation is the point here. Japanese-American, etc. If what makes someone American is that they were all born here, rather than Mexican, or Japanese or however, then they have no reason to call themselves Japanese-American.
Under this proposal, they cannot ever become true Americans, despite being born in America. This is a problem. It delays assimilation, because you are putting up extra hurdles for those who are already in America.
