I unironically believe that no one could actually condemn this without either appealing to their "eww"ness (basically appealing to their sense of disgust which has minimum to no value) or to divine command theory in which case the burden of proof would be on them to establish it
besides ad hominen and expression of disgust some people made a consequentialist argument against it saying that normalizing it would cause harm or a larger-scale
it sounds reasonable until u point out that it's on them to prove it'll have a high possibility of leading to real-
go to the comment section and quotes and you'll see that most people disagreeing are either calling me incestuous or saying that it's wrong because it is, which would be crazy if we condemn moral acts based on only intuitions
It's funny how many hoops you have to jump through to show to normalgroids that incest under these conditions wouldn't be morally wrong but you'll always get ad hominems and immunity to nuance or critical thinking thrown at you
@asylusma I ratio'ed you and my comment section is more interesting
