The senate bill says what it says. You have the complete text. Show me where it says what you claim.
What I see is a trap for evolutionists. If you can't challenge a theory then it isn't science, it's doctrine. The author is trying to trick you into treating science exactly as he would treat religion.
Part of the problem here is that there is no competing scientific theory. We don't consider alternatives to gravity, the atom, germ theory, electromagnetism, or the rest of the well-established scientific foundations in grade school, either. Despite the fact that there are nuances to them that may hint at exciting new science, the core systems are supported by so much evidence, that it is appropriate to just state the prevailing theory, the supporting evidence, and the implications. Teaching a "controversy" is itself a lie, because there is no controversy on evolution within science. This is just science vs. not-science, and that's for philosophy class, not Biology. As soon as you mandate that teaching a lie is protected and immune from discipline, you're not teaching science anymore.
