So I’m going to chime in and point out it goes beyond creationism. Some of the “approved” materials used by private schools are wall-to-wall indoctrination into a very narrow wingnut mindset, wherein right-wing ideology is presented as factual, and the whole of history and philosophy is channeled through partisan lenses (link to Wonkette’s review of a Christian textbook). It’s teaching kids to be JBS wingnuts. That’s part of what Jindal wants government money to go to (note: the board making decisions about where money can be allocated also said “No” to an Islamic school, so religious freedom isn’t an excuse.)
