Incest, bestiality, pedophilia, necrophilia
Bestiality -- What part of "people" did you not understand?
Pedophilia -- What part of consensual did you not understand? And before you go off, there are "age of consent" laws in every State of the Union, minors can't give their consent, and an adult is not allowed to accept the consent of a minor child.
Necrophilia -- The rights of the deceased are in the hands of the next-of-kin until burial, so if you can get Cousin Billy to say OK to your humping dead Aunt Millie silly, you go boy!!!
Quit it with the absurd boogeymen...no one is buying.
