I'm generally not sure if you can separate the coercion from the physical act, as the victim is fucking the goat after all, even if under duress. They are a victim of that crime.
However, I'm also mindful this conversation is rather close to the entire, can a women rape a man if the man gets a nob on during the event.
I suppose the pertinent question becomes is it more likely this adminstration cares about the victims of bestiality or more likely someone was filmed fucking a goat or throating a horse.
They are trying to bury the case by retrospectively changing the rules, clearly.
