Amoeba-Americans already have all the same rights as other Americans. Note that rights and freedoms are different, something the anti-vaxxers had problems with when they claimed that their rights were being stolen from them, when the only right they had there was the right to refuse vaccination, which was respected. They never had a right to work or dine where they can be legally be discriminated against.
Regarding guaranteed rights, Amoeba-Americans have the same rights as their terrestrial, air-breathing counterparts. First Amendment protections. The government cannot censor anything they might have to say, nor prevent them from assembling, nor worshiping the God of their choice. Their Second Amendment rights are the same as those of babies. Fourth Amendment, too. If indicted, they're entitled to council, a speedy trial, the right to address their accusers, etc.. Nowhere in any of those amendments does it say that a clump of cells can be treated any differently than babies, children, or older Tetrapod-Americans.
