"An internationally known Princeton "bioethicist" and animal-rights activist says he'd kill disabled babies if it were in the "best interests" of the family, because he sees no distinction in the child's life whether it is born or not, and the world already allows abortion."That's the money quote, but you really should read the whole thing.
I agree with him on one point: I also see no difference as to the ethical and moral status of a baby, whether born or unborn.
As for the rest, the man is a sociopath in the purest definition of the term; in that other human beings are unreal to him, and have no inherent moral or ethical value; not does he have empathy with them.
This is also the same guy who thinks that it's ok to have sex with animals, if they like it; and that pedophilia is OK if the children consent; among other disgusting ideas.
And this folks, is the lefts most revered "bioethicist".
