I actually agree with a lot of this. I have no issue with Bible classes being an elective, and I think the argument that kids who choose not to take it will be ostracized is over the top. An elective allows those who want it to take it, and those who are interested have an opportunity to learn about it. For me the issue occurs when those who are not interested are subjected to forced prayer and Bible classes. As you said, that’s not how Christianity works. Nobody should be told they can’t pray, and nobody should be told they have to.
