So, I probably should make one last effort to say something and give up: People disagree with evolution. Period. Some of them are very intelligent and knowledgeable people and you're going to have to find a way to deal with that. To try to classify those people as ignorant, conservative christian, whatever, is just a cheap shot. But the classifications themselves are pretty bogus, in my opinion. You can find people in just about any discipline who do not accept evolution, and those who do accept it, including what I would call conservative christians.
I think that for the purposes of this thread the class of anti-evolution arguments being discussed are those that can be shown to be demonstrably false yet still used by a subset of anti-evolutionists who all just happen to be
fundamentalists christians. I am sure there are a number of conservative christians who would take slight to your assuming that anyone would take the anti-evolution argument and correlate it with conservatism.
The point is that there are still people who DO USE the moondust argument and they almost exclusivly use it from the pulpit or equivalent. There are people who still believe and preach that the earth is 6000 years old. There are people who believe and preach that a worldwide flood is responsible for all the geologic features on Earth.
All of these ideas ARE based on ignorance because given enough factual knowledge it is child's play to demonstrate that they are false.
What is worse, these people want every child in the USA to be forced to learn about these beliefs as if they WERE actually valid.
Of course, biblical creationists are committed to belief in God's written Word, the Bible, which forbids bearing false witness; --AIG (lest they forget)
