It seems to me that of all cetaceans the orcas, known to all as killer whales, whales who kill, who have never denied the designation as killer or shown any remorse for their killing even of other cetaceans, have the least grounds for freedom. Dolphins and other cetaceans may kill in self-defense or mating combat, but only killer whales have earned the name killer. Rather than give then their freedom to continue their killing, ought not we continue to give them usefull, productive lives in public service as entertainers?
They actually seem to do better in their role as entertainers than their Human audience does at serving to their own species, are better servants like the Best Servant of all, He Who gave up all to become Human to serve Humans.
