Since you know not every child is Christian, why don't you understand why it is wrong to have Christian prayer in public schools?
This is sort of a spin off from the post about the teacher removing her religious posters from her classroom, etc. In that post some Christians objected to their God being "taken out of schools" in the form of school led prayers, etc. My question to them is this:
What is it about the OTHER religions and non religions of people and their children other than Christians that you do not understand? If you understand the fact that not every child is Christian, then why don't you understand why it is wrong to have the Christian God represented in public schools?
