The 14th Amendment is completely irrelevant and not helpful in this debate. It simply does NOT apply.
The 14th Amendment was written to grant rights to former slaves.
It is INCLUSIVE.
It is NOT EXCLUSIVE.
NOWHERE does the Amendment state that there are not other ways to gain citizenship.
NOWHERE does the 14th Amendment say that Congress can not make laws that include other methods of gaining citizenship.
But they can. However since they only have the power to define rules for naturalization, any methods they pass as a matter of statute law, necessarily define only naturalized citizenship. The Constitution, as made clear by the 10th amendment, declares that Congress only has those powers delegated to it, and is sometimes forbidden to exercise those powers in certain ways, such as to infringe upon the right of the people to keep and bear arms. But just because a power is not forbidden to Congress does not mean they have it. Even most states don't work that way anymore, although they once did.
First, I tried to say its late and I don't want to get into this now. Its obvious you have come here for an argument, and I have wasted to many words and to much time saying not now.
You act as if the rest of the world doesn't have a clue. This subject has been debated here for about one whole year. As you have been around since 2005, I expect that you would have got this out of your system back in 2008.
If you want to know the facts, I encourage you to spend the time to chase the threads already posted on this subject. If you don't care about the facts, and just want to yell, we can handle that too.
