Are we Darwinists - where we live and let live? Or are we nurturing as a society? There has to be a standard of living that we decide to support.
My parents were very permissive when it came to animals. As long as we earned the money to buy them and built whatever structure it was they were going to live in we could have any kind of pet we wanted. They would have let us have a rhinoceros if we could have afforded it.
