A replica guillotine in the middle of a children’s museum?

The local children’s museum, Kid City, recently opened a new medieval room. It’s a fantastic exhibit that includes castle walls, towers, a crossbow range, a tavern, a brick factory, and what I can only assume is a bladeless guillotine:

I am not opposed to the replica guillotine – in fact I kind of love it – but I can’t imagine that there aren’t a hoard of namby-pamby parents and guardians who take one look at this thing and shield their child’s innocent eyes and flee.

How does Kid City get away with this?

By the way, I love Google’s definition of namby-pamby:

“lacking energy, strength, or courage; feeble in behavior or expression.”

It’s sort of perfect. Don’t you think?
