We are proposing a re-definition.
That's not in the least what I'm suggesting.
Dolphins cannot participate in our society by agreement. They don't understand what participating is. They're captured or born in captivity and then trained to perform a few tricks. They are beautiful and fascinating, but they have no contributions to make to the fiber of our society that can't be made by other animals, machines, or even simple objects.
They are able to do nothing further. Giving them a new status is just semantics. They are fundamentally not functioning members of our society. Not individually. Not as a species.
Poor people don't contribute to our fiber of society in a way that can't be replaced by machines, said Mitt Romney.
