Yes, I know the language sources. But the move is on, I think, to relabel the act from "bestiality" (a well-known term that invokes revulsion almost universally) to "faunaphilia" (a term that is not well know and thus can be "marketed" differently).
Umm, I added the faunaphilia tag, Seattle Pi didn't. Apologies. Didn't mean to start a debate over it.
I just obsess over diction sometimes. Call it whatever you like, though, sex with animals is sick.
