I wonder what's next.
A child band of thieves that say things like "A good thief never steals anything from anybody?"
Of course, they could go with the classic "It's only good to steal things back from people who stole them from you or others in the first place," which still fits in with the nature of both pirates and thieves (albeit heavily sanitized) but parents would still complain and it would still be heavily sanitized to what pirates and thieves actually do.
