Why should the Bible be taught in public school?
There are churches on every street corner in America that teach the Bible and it's infinite interpretations - take your pick. FOR FREE.
We shouldn't be paying for it in the pubilc schools.
If there were thousands and thousands of free places where they taught English grammar, I would say stop paying to have English grammar taught in public schools.
This is simply being pragmatic - on top of obeying the law, of course.
Trump is not advocating anything official from the federal government nor is he pushing anything. He made a comment regarding what some states are doing. It none of the federal government's business what a state teaches. It is also none of the business of anyone who does not live in one of these districts.
