Religious Rights?

So today in play production class we went up to the library to do research on Alzheimer's disease because our one act play for competition is about that. So my friend Tatiana picked up a little list of books that have been banned in the school. 

The Bible was one of them.

I guess I should have expected it but I really wasn't so I was super surprised. The Koran was also one of the books on the list. I said something about being really surprised and my friend Kyle said "It's because they cause controversy." 

That got me thinking. Banning books that cause controversy seems like people don't want to put up with the arguments. Like they are afraid and they don't want a challenge. If people were so convinced that the Bible wasn't historically correct, or that God doesn't exist, then why are they banning the Bible...and even the Koran? If they think they are right, then they have nothing to be afraid of...correct? 

I don't know. This probably only makes sense in my head. It's hard for me put into words what I'm thinking sometimes. I mean, I'm not bashing these people. They can believe what they want. I just don't think it's right to ban the Bible or the Koran when we supposedly have free "religious rights" in this country. It makes me mad when the government is saying we have "religious rights" when, slowly but surely, they are taking more and more away. 

It just doesn't seem right to me.
