there have been displays on the news even recently of people who find the Arts unacceptable because they may depict genitals (Greek Urns, Renaissance Statues etc.),

so easily you will find around voices that could respond recommending that children be protected from exposure to the Arts.

(And - ironically - not from the obscenity of those very voices.)

I would note that there are such things as "children's encyclopaedias"; I might have had an earlier edition of this one myself as a kid: https://www.amazon.com/Childrens-Illustrated-Encyclopedia-DK...

(I wonder if they still put in the cartoon of the Aztec Blood Sacrifice?)
