This needs to be pointed out, because a disappointing amount of people either can't tell the difference, or simply assume that the two things go hand in hand, or are one and the same.
Necrophilia is an attraction to dead people. That's it. It doesn't imply any personal idiosyncrasies or tastes. You'd be just as wrong to assume it automatically comes with certain stereotype traits, as you'd be to assume that all gay men are effeminate, prancing pansies, or all lesbians are shaven headed butch types who wear dungarees.
Gore fetishism is one of those things that can affect an individual with an attraction to dead people, but it's by no means an integral trait of necrophilia. If you ask me, it's a manifestation of sadism, which is something that crops up in all sexualities. It's not peculiar to us as necrophiles, and I don't like it when its assumed that it's part of my sexual make up.
Thanks for reading. Rant over!
