This need not be said but at least should be mentioned: corpses cannot be physically harmed. Thus, if we factor out aspects like property violation, there is little that crops us to indicate necrophilia as a wrongful act.
Some might say having sex with the dead is unhealthy. But then so is smoking, driving, drinking, which we allow. Besides, corpses can be cleaned and can be made more hygienic than many living people.
Again it’s not clear what makes necrophilia wrong by definition, aside from property violation since the dead only matter to the living. If there was no living person who cared about the corpse in question, what would make violating it – whether through sex or mutilation or eating – wrong? It’s uncertain, but there’s little reason to support sending people to prison for merely having sex with corpses, if there’s no one to whom the corpse belongs.
Necrophiliacs may disgust us, but we cannot let our disgust filter out clear reflection on the subject. There is little reason to think the act automatically wrong. But being unconvinced by the arguments against an act does not mean one automatically supports or encourages it.
This is pretty much scraping the bottom of the barrel with respect to lack of sexual discrimination. Notice how a rabbit who will mate with corpses, will basically mate with anything, and in r, that is not only not bad – it is a huge reproductive advantage.
Again, the shift from K to r basically leaves the rabbits unable to grasp the older, traditional K-morals. The idea of someone who mates with corpses maybe having something wrong with them and being a poor choice as a fellow in-group member, or the idea of a behavior predisposing to disease and posing a risk to one’s in-group are so foreign as to be unable to be understood.
It is amazing, because they are obsessed with logical analysis, but given they have no natural grasp of what it takes to survive in the face of adversity, and they just are not designed for the real world, all of their analyses lack and real foundation in reality.
Of course we can’t discuss necrophilia without closing out with the late, great Sam Kinison.
