It goes deeper than just not teaching evolution. It is an attack on science by religion, for religious, rather than scientific, reasons.
The attack is broad, not just on the particular items they disagree with, but on the very methods of science. "Its just a theory" and the stickers are a case in point. That distorts the methods of science, and while true, conveys such a false impression that it amounts to a lie. "Teach the controversy" is another example; the controversy is not within science, but between science and a particular brand of religion. Again, this amounts to a lie because of its dishonest misdirection. (There are many more ways to lie than telling a flat-out falsehood.)
So, I guess you advocate dropping evolution and who knows what else for religious reasons; I advocate keeping them for scientific reasons.
I do not personally support dropping them for "religious reasons." I sympathize with those who support dropping them, but my reasons are political and ethical. I think the idea that dropping them will cripple science, and many of the other arguments for pushing evolution, are sheer hype.
I think the correct conservative position is to get rid of monopolistic government schools, but I'm a realiist enough not to see that happening soon, if ever.
