Also, mammals are fish. Happy birthday.

It’s like Pluto all over again.

Wait... What is your take on Pluto? Are you drawing a similarity as a taxonomic exclusivist, i.e. "Birds≠Dinosaurs::Pluto≠Planet" or as a taxonomic traditionalist, i.e. "Classifications are and shall ever be as they were in the 1960s"?

Because the conclusion we should draw about your opinion on the planethood of Pluto depends absolutely upon the taxonomic philosophy you adhere to as the lens through which you make the comparison.
