The recent controversy over an episode of the children’s program Postcards From Buster, which featured the main character learning about sugar mapling from a family with two women at its helm, has sent PBS scurrying for cover, and has conservatives once again suggesting that public broadcasting is incurably liberal. Caught in the middle of the firestorm is an 11-year-old girl from Vermont who was to be the star of the episode. The “immoral” family featured in the show is her family, the two mothers are her two mothers, and she doesn’t quite understand what is so objectionable about her demonstration of how to tap a maple.
