The cover image itself is not pornographic, IMO. If it were an image of people actually having sex, then yeah let's talk about that. But it's not. It's literally just a naked ass.

Gotta be honest, I think you're reading a lot more into that comment than is necessary or warranted. That comment did not advocate for showing pornography to children. It is not "obvious". You made an assumption. I read it as a direct response to 'or another named just "Porn" with a giant naked ass on the poster.' in the OP.
