I don't actually disagree with you, but it is an interesting argument of, "Pedophilia, or the imitation of it, is wrong... except in cases where it's already become normalized, and then I guess it's okay even if it's not for me."
I am not a fan of it, but animated pedophilia is not on the scale of "things that need to be banned" for me. You also have things like guro and other really disturbing animation, but I don't necessarily think it should be banned either. I try to be consistent with "if there is no victim, there is no crime"... though stuff like this certainly pushes that.
