"Nudity is widely defined as the exposure of genitals and when said figures not only are creatures and beasties, but have no genitals to expose, they can hardly be considered to be nude just as."

Moralists are perverted people that are able to see perversion where nobody does.
You see a moster that has no sex, they see their sexual organs.
You see Donald Duck sleeping in bed with his nephews, they see an act of paedophilia.

Stupidity also evolves!
