BTW, this exact issue went to the Supreme Court on a case back in 1986. Several parents believed the standard English textbook was ungodly, requested special accommodations, and these were granted to 9 students at three different schools. All these people were happy as were their schools. One other school principal refused though and so two families were left out. These parents were unhappy and went to the school board to complain about it. The school board was affronted and voted to ban all special accommodations and enacted a rule that only the textbook they approved was permitted and no other, effective immediately at all schools in the district. The 9 happy students then were retroactively banned even though they, their teachers, and principal were OK with the arrangement. Some were suspended when they refused to read the ungodly textbook (a generic Holt reader, BTW, no idea what their issue was with it maybe stories about dinosaurs?). Several families then withdrew their kids from school.

So this unhappy situation goes on a long path all the way to the US Supreme Court.

First stop: district court. Ruling is textbooks are religiously neutral and can't possibly violate whatever beliefs they have.

Second stop circuit court said in light of Yoder etc it's not the courts to decide what is a real religious belief or not and district court was wrong.

Supreme Court looks at it. Says circuit court is right that courts can't decide what's legitimate religion but it doesn't matter because although a school may make special accommodations they don't have to and there's no right to a public education. If you don't like what the school offers for religious reasons you can homeschool or choose private, the end, that's the law, and that law is how it still is until today. Of particular interest is that US Constitutional law is currently that no one has any right to a free public education.
