I'm sorry, but the amount of people on this thread who have their own notions of what constitutes as natural is getting silly. If we were to agree on what natural is we may actually get somewhere.

This one's interesting: "10. Being in a state regarded as primitive, uncivilized, or unregenerate." Certainly sounds like like a rapist could fit into these descriptions to me.
There's actually a lot more definitions in there than I thought, but take a look over, and tell me how rape is unnatural according to some of those definitions.
