I, personally, am a creationist. I naturally prefer the teaching of creationism to that of evolutionary origins, however, I would honestly prefer neither to be taught as science since neither really stand up in the face of empirical methods of study. But my view of science is far narrower than most.
The key in any situation where the parent differs with the material being taught by a teacher is for the parent to be involved in the education of their child. Absentee parents who simply let someone else educate their children completely deserve whatever that education produces. There is nothing that prevents a parent from supplementing classroom education and I would think such augmentation would be welcomed by concientious educators and ultimately beneficial to children.
All my kids will be homeschooled so we have absolute control over what they learn and I intend to teach creationism from the standpoint of religious studies and evolution from the standpoint of speculative science and in order to provide a far ranging education for my children. Critical thinking will quickly reveal the weakness of dealing with either creationism or evolutional origins as empirical science, and I want to foster that kind of critical thinking in my educational efforts with my kids.
