A 1983 two-part episode of the sitcom "Diff'rent Strokes" is about child molestation. It's clear from both a message delivered by Conrad Bain, who played the father in the series, and the content of the show itself, that it was intended as a "public service" to educate people on child molestation.

While the show is educational in a sense, it can't be forgotten that Hollywood protects star pedophiles and many child stars have been abused and exploited. So, the motive for this show being done have to be suspect.

In the episode, the character played by Gary Coleman, Arnold Drummond, and a friend of his, are groomed by a child molester, played by actor Gordon Jump, who gives them ice cream and pizza to lure them in, and then wine. The grooming experiences are presented in a lot of detail, and seem to accurately portray how a molester would use twisted logic and deception to gradually draw children in. It's disturbing to watch.

I was trying to think of some of the social context for why this show would be made, and perhaps it was due to high-profile cases of child abductions and murders like those of Adam Walsh, Johnny Gosch, and the Atlanta child murders in the prior year or two. By doing such a show, Hollywood be putting itself in the "crusader" role.
