I hear what you’re saying, but a bill that allows students to critique, review, and analyze evidence for and/ or against evolution can only be a good thing, because there should never have been a bill or other hindrance against reviewing any scientific theory, free thought or idea. Whatever one believes should be open for debate, in my experience this is how people learn and not just accept what is told to them.
I agree with what you’re saying, to an extent. Yes, ideas should be critiqued and carefully reviewed and children should be taught to think critically about what they are told.
However, there is a difference between teaching children to think critically and bringing religious ideology into a science classroom. It may be nice to think of “Intelligent Design” as a viable scientific idea, but it simply isn’t. It’s creationism, it’s religion and it has no more place in a science curriculum than does Yggdrasil the World-Tree.
