I agree with what you wrote but have you ever heard of a teacher saying such a thing to a class? Is this really an issue? Is it necessary for the OK house to pass a bill preventing teachers from getting on all fours and barking like a dog also?
Yes, I think it is an issue in many classrooms, at least in public schools. The liberal worldview that invades many schools includes an anti-religious bias. The question of evolution and what that means in relation to religious belief comes up when this topic is covered, I expect, and my teachers treated it fairly; I suspect some others would not.
What the legislature, or school board, should do about it is difficult to say. Keeping a close eye on the curricula, I suppose, take a good look at the textbooks (probably comes up more in history and whatnot than science) and be responsive to student and parental complaints.
Well, okay, maybe in Oklahoma ...
