There is no political lean for classical music or children's programming. But that's what got cut.
Small correction here. Religious conservatives lead by the late Jerry Fallwell and the late Phyllis Schlafflly (may have screwed up spelling of her last name) were protesting the Children's Television Workshop and programs such as "Sesame Street," and "Mr. Roger's Neighborhood," since the late 1970s. Their basic charge was that these programs were teaching their kids values different than the values (supposedly) found in the Bible. Basically, these criticisms were an early form of criticisms of diversity, equity, and inclusion--though nobody knew it at the time.
The programming wasn't "widely recognized." If it was, they would not have received the money in the first place. There was no requirement for any radio or TV station to air any programming it objected to. These are the same people who object to Colbert and Kimmel, and neither of them use taxpayer money. This isn't about "balanced programming." It's about shutting down the media. This isn't an isolated thing.
