The first amendment of the US constitution grants freedom of speech to all persons. Courts have interpreted that first amendment applies broadly, even to non-citizens.

I find it hard to believe that THIS Supreme Court would re-affirm this decision if it ever came up.

You raise a good point, but I'll opine that I don't think it's necessarily a broad definition of "person" that includes non-citizens.
