Thankfully we've (generally) been able to hold the line against intellectual affirmative action, cultural relativism and the like in the science curricula.
Creationism, environmentalist pap, ethnic/gender-group oriented feel-good tokenism in the history curricula, etc: it's all of a piece. If we weaken our commitment to rigorous, hard-nosed academic standards in one area -- insisting that ideas are included/excluded in the curricula because they have objectively succeeded/failed in the relevant field of scholarship, and not because some ideologically motivated interest group likes/dislikes them -- then we weaken our resistance in all other areas.
IOW, you make a very good point about hypocrisy. Conservatives have traditionaly stood for no-nonesense curricula. We need to maintain that standard, even if some of us may have doubts about evolution, and challenge liberal relativism in the sciences, social sciences, and elsewhere, from that ground of consistency.
I happen to be an evolutionist myself, but for those he think that some sort of creationistic theory may one day prevail, bear in mind that this prevalence may not be reflected in future curricula if the precendence of teaching "both sides" is established now. Even though an evolutionist, I aver that if evolution should ever be supplanted by a superior theory, then evolution should be excluded, just as creationism is now.
