Earlier quoted context omitted.
And those of the rest of the world. Especially those of us in X eyes countries.
Hey may have defended the rights of people in the rest of the world, but only American citizens have rights protected by the US constitution.
Untrue, though this is a popular myth. There are a few Constitutional rights explicitly restricted to citizens (voting is the big one), but pretty much all the rest are rights of people generally that the government (either federal or state, depending on which Constitutional provision is involved) is restricted from intruding on. Both the plain text and the case law of the Constitution is inconsistent with this “only American citizens have rights protected by the US constitution” view.
There is some case law that certain actions by the US government affecting noncitizens outside of the US are not limited by certain provisions of the Constituion that would affect actions that were either within the US or directed at citizens (or, at least, that such actions are not subject to legal process in the federal courts, which amounts to the same thing), but the particular exception is quite narrow.
