Majority opinion here on /. may be that creationism/ID should at most be taught in a religion course, not a science course. However I find it interesting that nobody has commented from a constitutional or federalist viewpoint.
Shouldn't the power of federal or state governments continue to be limited such that local school boards can do as they please? National or state-level standards can be established via standardized tests etc. If local school board buffoons want to teach garbage, then their students can be left to cry when they are unable to pass standardized tests and continue on to higher education outside of their localities.
Sure, I'd like to teach all kids everywhere the things I believe are correct & useful, but I'd most prefer that government leave me alone to decide for myself. Nationally mandated curricula sound good in this case, but what about if that curricula also includes a strong bias toward socialism in its sections on Government & Civics? Or only highlights the evils (and not the benefits) of gun ownership? Or only presents certain sides of sensitive historical topics? Or *insert issue of your choice here* ?
