I tend to accept the idea that these animals have been idealized.
Most liberal left hippy dippy propaganda, such as the superior mystical nature of cetaceans, is nonsense.
It serves as lies which further serve to inculcate world views that make one side with Government intrusion as in this current incident with OSHA and Seaworld.
I’d have no problem with a law that banned killer whale shows. But this is rule by fiat based upon whim.
