Holmes, what do you mean by "splintering of education"? Do you mean that colleges would have to accept students with different levels of understanding of mainstream concepts in science, history, etc.? I don't see why they should have to do that.
Or do you mean splintering of secondary education? If so, it's already splintered, simply because there is already home-schooling, "Christian Academies" etc. where evolution and semi-related concepts aren't taught, or are taught only as something bad and wrong.
I agree it's hypocritical to suggest that it's OK for anti-evolutionists to go their own way, but not for Holocaust deniers etc. to do the same, but I'm skeptical about what effects such things would have on education in general.
My wife is a biology professor, and she's had students who were brought up to disbelieve evolution, and some of them turned out to be good students, while others weren't (same as the regular kids).
