@feld Legally it doesn’t make sense to allow miscegenation but disallow cousin incest, as the former causes significantly more health problems for the child than the latter (especially in the case of very genetically distant people like Europeans and black Africans) youve already ceded the “health of the child” argument as insufficient. Beyond that, legal precedent in America is pretty clear that nothing involving the law and sexual morality much matters beyond the consent of the involved parties.
