@dr2chase Reducing white women to the status of chattel is important to the project; they can't do that without reversing the demographic transition as it applies to white people, too. And that unconcerned "kid died of measles" couple may well be representative.
They've deeply internalized "women, cattle, and slaves" and a Late Romantic "survival of the fittest" which ignores the actual environment and supposes some ideal person. Facts are not much involved anywhere.
