The constitution has a clear definition of who is a citizen
What's also interesting is that until the 14th Amendment was "passed" there was no such thing as a US citizen!
Article I, section 2: "No Person shall be a Representative who shall not have attained to the Age of twenty five Years, and been seven Years a Citizen of the United States"
Article I, section 3: "No person shall be a Senator who shall not have attained to the Age of thirty Years, and been nine Years a Citizen of the United States"
Article II, section 1: "No person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President"
Clear references to US citizenship existed in the constitution before the 14th amendment. All the 14th did is clear up some of the confusion (although judging by McCain's campaign, there is still cleanup to do).
Now, as far as non-citizens not having rights, I think it's up to those of you claiming this to prove how that's not crazy talk.
The word "citizen" doesn't occur in the bill of rights. It occurs in other parts of the constitution, but not in the BOR. The aforementioned preamble says "in order to prevent misconstruction or abuse of its powers... further declaratory and restrictive clauses should be added".
That means that the purpose of the BOR (original intent) was to declare rights of the individual and also to bind the actions of the government. Citizenship doesn't enter into that equation.
Now let's jump straight to a stellar example: the guns. Why not let illegal immigrants defend themselves? The specious reasoning we employ to deny them firearms is the same that we use when passing and enforcing drunk driving laws. If the potential to kill others doesn't stop an individual from engaging in an activity, then additional slap-on-the-wrist laws won't, either.
Illegal immigrants who are here merely to try to provide for their families have every bit as much right to defend themselves and their families from predators as I do. The majority of them are also as likely to fire randomly as I am. Moreover, the bad ones who are likely to actually fire on other law-abiding citizens or INS officials are likely to have guns to do it with despite our current draconian firearms laws. If citizens can get them illegally, why can't illegal immigrants?
So the only effects denying illegals their human rights can possibly have is to 1) needlessly endanger their lives, 2) make the entire issue more confusing for everyone, as the law applies only to a privileged caste of individuals (citizens), and 3) the unintended effects nobody will contemplate - such as the slippery slope question of who the BOR really applies to.
Our work should be to get it to apply to everyone. Anything less is a reduction in liberty.
