Yes. A few things to keep in mind. First the “we the people” in the preamble is the subject of the sentence, that’s who is MAKING the Constitution, not the list of who it applies to. Then over and over in the Constitution is says “person”, no limitation on who is a person. And finally, and this is the big part, the Constitution is mostly limiting government power, especially when you get to the Bill of Rights. The government can’t do this and can’t do that. Doesn’t really matter who the government can’t do it to, it just can’t do it.
Also keep in mind there is the question of when said government knows, and the government having the burden of proof. One way or the other the government has to ACT like you’re a citizen (or legal visitor) up until it can prove you aren’t.
Yet the left can ignore or infer whatever they want to, such as denying us right under the 2nd amendment. The 2nd cannot be more clear on its meaning and yet...
