And, that does kind of lead to an odd question - what if someone wishes to will his/her body to a necro?
I mentioned that several times earlier.
Having sex with corpses and especially keeping corpses stored away in populated communities, brings an incredible risk of disease spread.
The guy who brought necrophilia to my attention believed that necrophiliacs should both need written consent from the deceased, and regulated medical grade facilities for preserving corpses.
I looked these guys up once, and they have their own communities and everything. They even classify each other into different grades of Necrophiliacs. That leads me to believe that the category is a lot larger than we might realize, and that solutions to coexist may be overdue.
