In my anti-gay-marriage apologia, I mused about what new taboo the cultural left would set its targets on once gay marriage became the norm. Protein Wisdom has found it:
“after-birth abortion” infanticide.
Abortion is largely accepted even for reasons that do not have anything to do with the fetus’ health. By showing that (1) both fetuses and newborns do not have the same moral status as actual persons, (2) the fact that both are potential persons is morally irrelevant and (3) adoption is not always in the best interest of actual people, the authors argue that what we call ‘after-birth abortion’ (killing a newborn) should be permissible in all the cases where abortion is, including cases where the newborn is not disabled. […]
This is what reason does when divorced from first principles: it finds a rationale for any kind of behavior, and then determines, since a rationale exists, that it must be ethically acceptable. Any argument against the behavior must thus prove the rationale invalid, or else, however impeccably reasoned from first principles, said argument must be “irrational.”
So the left is readying itself to declare more and more humans to be un-persons.
