A difference of "one notch" is a small difference of degree, and therefore not one of kind. Furthermore, the nature of a living thing does not change until it dies, even if it's a caterpillar. When a caterpillar has become a butterfly it reproduces, thereby making... more caterpillars. Cats make kittens, dogs puppies, and humans children, all reproducing "after their kind". It follows that if children differ from domesticated animals only by degree, not nature, all adults are also bestial.
So why, exactly, should anyone care what someone who, by his own necessarily implied admission, has nature of a domesticated animal thinks?
