That's because evolution is based upon actual science and belongs in science classrooms.
Funny that those who are interested in ID are perfectly happy to have Darwin taught in the schools, but Darwinists simply can't brook any competition.
No, the ID crowd and other anti-science groups have been working hard to eliminate evolution and by extension, any other science facet that might threaten their narrow minded fanatic version of the Bible from science classrooms - hence the court battles against science in Kansas and Ohio.
BTW - there is no such thing as a Darwinist. That's more inaccurate than calling someone who recognizes that jets fly a "Bernoulli-ist" or that a multistage rocket was capable of reaching the moon a "von-Braunist."
There are those who are educated in science and those whose ignorant fear propels them against it.
You mischaracterize the Kansas (and probably Ohio also)debate. Because you are misinformed or misleading?
1) understands biological evolution, descent with modification, is a scientific explanation for the history of the diversification of organisms from common ancestors.
2) understands populations of organisms may adapt to environmental challenges and changes as a result of natural selection, genetic drift, and various mechanisms of genetic change.
3) understands biological evolution is used to explain the earths present day biodiversity: the number, variety and variability of organisms.
4) understands organisms vary widely within and between populations. Variation allows for natural selection to occur.
5) understands that the primary mechanism of evolutionary change (acting on variation) is natural selection.
6) understands biological evolution is used as a broad, unifying theoretical framework for biology.
7) explains proposed scientific explanations of the origin of life as well as scientific criticisms of those explanations.
This is what you're having a cow over?
Summary of your argument: Evolution is science and ID is not. Because I say so.
Don't you get tired of repeating that mantra?
