If the beings so depicted are gods, then how can these picture be considered "obscene"? Maybe pictures of mere humans in whatever positions/alignments/configurations that the gods indulge in might constitute "obscenity", but because the pictures show gods doing something, doesn't that by necessity make such pictures non-obscene?

You know, sort of like how being a soldier in a war means you can kill people and not be guilty of murder. Being a god means that whatever you do is sanctified.
