The problem with Kansas is not their religion, and not even that they want their religion taught to their children. The problem is a failure to appreciate the way bodies of data naturally divide and associate according to relevance and inherent logic (at least inherent as far as we can see). The notion of one class of data dictating that another class of data should be suppressed from sight is abominable because it informs the individual that it is not able to discriminate.

Not only that, but the notion that teaching scientific data in its own proper context might undermine the Cosmic Truth of revelational Xianity kind of shows a low esteem for the power of that set of truths.
