All or nothing

Religion and Evolution are the two aspects of what happened in our history that are "touchy subjects" in the 1920 and even know. but back in the 1920's it was illegal to teach evolution, but today its illegal to teach Religion. hmm that seems like we dont know what we want to or can teach but when it comes to it Evolution and Religion are two theorys that have evidence or a way to show that they have happened. So i feel that All of it should be tought or none because one or the other would be wrong in someones eyes.
