I watched 3 episodes of World's Strictest Parents.
Theme. The kids who acted out came from single parent homes. The families they are sent to have two parents and all that jazz.
Implication. If you live in a nontraditional home, you will become near delinquent. If you live with two parents, you will learn responsibility, integrity, respect, and how to be a hard worker.

More and more people are becoming products of non traditional homes, and the show is reinforcing stereotypes whether the viewers know it or not.
