As an afterthought to Mr Noodle (and please, take this as it is offered, which is with the greatest of personal respect to you, who I believe to be a fine person), pretending that there isn't an effort to insert Christ and Christian mores into our schools and public arenas doesn't make it not so, either.
I think the expansion in the effort to remove religious intrusions into secular areas is in direct proportion to the expansion in efforts to add them in the first place. The Constitution provides a mandate to keep Church and State separate, and that includes my Pagan theology, too.
For example - Just because Darwin happens to jive with my personal take on Creation doesn't make teaching Darwin religious, but teaching that Jehovah God (tm) created it all (even if it is disguised as "Intelligent Design", which, let's all be honest, is Creationism unless you also teach that it might have been the Flying Spaghetti Monster, aliens or a chem lab accident on Delta Tauri) is, in fact, religious, since the whole concept stems from the Bible.
I would have absolutely *no* problem with Creationism being taught as mythology, along with my own beliefs on the matter.
