There's no animal I'm aware of that has a mental capacity beyond that of a child. We don't think children are capable of giving consent - are we clearing the way to legalise paedophilia too, or are there animals with the mental capacity to provide informed consent that only lack the ability to communicate that consent?
Spoiler: It's not a communication issue. If this technocratic psycho was more concerned with actually contemplating the morality of the question, and less focused on rearranging the insides of a parrot, his takes might be a little less monstrous.
