There has never been a restriction on individual prayer in school. What this is about is STATE SPONSORED prayer. I know that as I assume you must know that as well but it makes for good politics for those less aware of the wordsmithing you perform. The first amendment is pretty clear in what it intends and based on the source of that amendment, yes, the term separation of church and state is a real concept. It was one of the pearls of wisdom in our constitution. Therefore this attempt to chip away at the parts of the constitution you dislike while emphasizing other parts (second amendment) seems to me to be less about the constitution or even what is happening in schools than it is to keep your voter base energized.
