Read the story whence comes the quote here.
Post-birth abortion, i.e. slitting the throats of infants and five-year-olds and draining their blood into the bronze bowls of the gods of convenience, is justified on the grounds that infants and five-year-olds are not self-aware. People with Down's Syndrome or dementia are, of course, unselfaware and inconvenient as well, so they could get the same treatment.
Here are a couple of candidates for post-birth abortion I know. Well, I suppose I'm the candidate. These are the humans I engendered with a willing female. But circumstances change, you know.
Look at the stupid, vacuous look on the face of these juvenile humans. You can tell they haven't reached the self-awareness phase.
Here is a human transitioning from infant to juvenile. She appears to be pretending to be a mother, but this behavior is purely mimetic, and in no way reflects the spark of imagination.
Finally, I would like to notify my father that when he does lose his mind I'm not going to be putting up with him. It will be better for me, I mean for both of us, if I slit his throat.
Is that cool, dad?
