Yes, non-religious folks should control secular education. How can you think otherwise? As I said, religion should be taught about in secular education (like in a Religion & Ethics course), but it should have no determination regarding the curriculum. It’s bafflingly absurd to think that it should in any way. In no way should religion dictate terms to a secular school or school board, any religion.
You say you can’t research the Batley school, but you are opining on the RE & specifically how it fits into the school’s curriculum? Please elaborate.
Again, if you can’t see that the minutiae is stifling a larger debate, I don’t know what to say. It could very well be an overzealous lout of a teacher proselytizing against Muslims; if this is the case, the teacher should be expelled. But, if it is shown that the teacher was the cause of the furor, then the materials that caused the furore should be allowed to stand & more care given to how the materials are used in the future.
But the materials shouldn’t be censored due to a thick cnut teacher. Like you said, they’re just materials. You shouldn’t hold anything against them specifically.
