I Don't Get It

This story from today's NY Times raises an issue that I've never been able to understand.  Maybe it's my own background as the child of people in the sciences (though I count myself woefully ignorant about science); and to be fair, the story is short and does not provide much detail about what the "supplemental materials" include.  Let's set aside the questionable constitutionality of any policy which would take up significant space in the science curriculum "disput[ing]" evolutionary theory.  Assuming that the debate is about whether to teach evolutionary theory in the science program of public schools, I do not understand how anyone could sensibly oppose that.

UPDATE: My link seems to go to a different story than the one I found yesterday morning, and I cannot find the earlier one.  The new story also indicates that the board itself (including the Republicans on it) was focused on an important but uncontroversial issue, a vote to approve supplemental materials which, it seems, are in any event non-binding recommendations to the individual school districts.  Some of the people attending the meeting did wish to discuss the more controversial matters, but that did not occur.
