I don't know about sneaking it in. I remember following the whole thing on TV. It didn't look a back room operation (like Obamacare) to me.
Just remember both Intelligent Design (ID) and non ID are "theories". It takes just as much blind "faith" to believe in non ID concepts, such as evolution or the big bang, as it does to believe in Genesis. In effect both are mankind's attempt to explain the unknown and that makes non Intelligent Design theories just as dogmatic and therefore just as religious. Let them teach both, no harm in that.
