Are humans who identify as non-humans a suspect class?

[Mr. Reactionary]

If someone who is a human and a citizen of the United States claims to be a non-human, an "alterhuman", an "otherkin", or some similar form of "trans speciesism" does this rise to the level of suspect class under federal civil rights law entitling the claim to special civil rights protections?

I dont see how it does, but apparently many on this forum seem to. What is the legal justification for this argument?

[Mr. Reactionary]

I don't see why it wouldn't just be an extension of gender/sex being a protected class.

Could you please elaborate? I still dont understand how anyone could have this viewpoint but its been presented to me as a given without need of any explanation. Like how can a human say they arent a human and be taken seriously?

[Mr. Reactionary]

     If a human being identifies as a non-human animal (say a deer or a cow, ad arguendo) and that identification is recognized as valid and legally protected, would that mean people would have the right to kill and eat them?

There is no logical endpoint to this "self-expression" nonsense. Any human who says they are non-human is both factually wrong and in need of serious counseling.
