The NPCs do exactly that.

They even misinterpret what they 'heard' the supreme beings talking about in the past.

Mare is the only 'young' boy around, and so he and Demiurge think that dressing like a Trap is how boys should dress, based on what Mare's creator said.
They are very ignorant about some things, since they never saw young children, and they never grew up.

In the light novel, Mare's creator is a H-game voice actress who likes young(looking) crossdressing boys and girls, and her brother, Shalltears creator, was an H-game enthusiast who gave Shalltear a bunch of fetishes, including necrophilia.
They fought a lot because nothing kills a H-game like hearing your sister as one of the characters, and they wrote the conflict into their NPCs biography.

In the light novel and Manga, the last line Momonga changed on Albedo was not 'Is a bitch' but was 'Is a Nymphomaniac/Slut'.
