"So, hands up all those who think that depictions of children being raped by animals has 'serious literary and artistic value'?"

While I'm not being "pro-child abuse", subject matter is not considered the determiner of whether something is art. As an example, take Andres Serrano's "Piss Christ" where the artist simply takes a photo of a small crucifix in a bottle of his own urine.

I'd rather stay in my lane than lay in my stain!
