Unfortunately for Douthat’s bullshit, eugenics wasn’t particular to progressives:
By mid-century, most mainstream Protestant leaders agreed that the nation needed to calibrate carefully the number and type of babies—and immigrants—allowed.
One central means for ensuring the careful calibration of procreation was shame. Indeed, the author of Fewer and Better Babies anticipated that working-class parents who produced more than two children would eventually be considered “anti-social, as criminal members of the community.” The anti-immigration and birth-control movements during the first half of the 20th century were linked by the sense that some people were beneath human dignity and would pollute “native stock American” bloodlines. The growing consensus during this era was summed up by the words of a Methodist clergyman from Missouri, writing for the Methodist Quarterly Review: “We should demand that each child born is worthy of a place in our midst.”
