I believe the author would argue that, if incest is your way of being in the world, then that is your moral judgment, and it is just as valid as anyone else's moral judgment and way of being in the world.

In the future, people will study the collapse of the Western World, which abandoned the natural principles of good and evil.
And just how in the name of the living Savior do you come to that mind-bending conclusion? Surely not baed on evidence of any kind.
