We definitely need more instruction in religion, cultural history and philosophy in schools. It's essential to understanding Western Civilization.
To accomplish what goal? What societal need is met by that?
Those are typically college level electives, not core curriculum, nor information most people possess or need other than some world and national history. I never had a course in religion or philosophy. Grade school is for teaching what a person most needs to know to benefit himself and society. The taxpayer doesn't benefit from grade school educational resources being directed to such topics, nor do most citizens.
More useful to them is basic language skills, basic math, basic science, essential history, basic civics and the like.
Nonacademic areas of value are home economics, sex education, and PE. These are things that actually benefit society and the students, not comparative religion or the influence of the Bible on culture.
After watching a hundred or so police interventions on YouTube that didn't end well (especially traffic stops), I'd add that they need to know their rights and responsibilities according to the law for the ones who want to be defiant have a chance to stay out of jail. You shouldn't have to learn that you are required to show ID or get out of the car when asked (told, really) to do so by having your car window smashed, being dragged out of the vehicle, being arrested, cuffed, and taken to jail, and having the car towed and impounded after shouting about knowing their rights, naming assorted Constitutional Amendments, giving cops orders, telling them that they need permission or warrants to conduct searches, etc.. Better to know that that will happen before it does. It might not help with the drunks, but it would be a service to would-be sovereign citizens, for example, who are susceptible to misinformation because of that ignorance of the law.
And let's not be naive. We know the intentions of the people that want to get their Bible into classrooms. It's not about students learning comparative religion or about the influence of the Bible on culture. It's not about education at all. Such people are neither academics nor educators. They're Christians working to regain access to the minds of children not taught Christianity at home or taken to churches. They're the same people promoting historical revisionism, book banning, and a national abortion ban: Christian theocrats. They lie continually like the three Trump SCOTUS nominees who lied about their intentions regarding overturning Roe when being confirmed.
We should believe these people when they tell us who they are and what they want. These aren't just fringe characters who nobody ever heard of and who have/had no influence. These theocrats are the kinds of people who rise to prominence in American Christianity:
- "The long-term goal of Christians in politics should be to gain exclusive control over the franchise. Those who refuse to submit publicly to the eternal sanctions of God by submitting to his Church's public marks of the covenant-baptism and holy communion-must be denied citizenship, just as they were in ancient Israel." - Christian Dominionist Gary North
- "I hope to see the day when, as in the early days of our country, we won't have any public schools. The churches will have taken them over again and Christians will be running them. What a happy day that will be." - Jerry Falwell
- "There will never be world peace until God's house and God's people are given their rightful place of leadership at the top of the world." - Pat Robertson
