The creationists/IDers are so hot and bothered to prove the biblical account of the earth's origin that they discount any idea, regardless of validity that says otherwise. Either that or they are so offended by the notion that humans and monkeys evolved from the same place. It could be both.
The reality is evolution is not about theology, but explaining the process by which we came to be. Evolution can even be considered theologically neutral, because there is room for in the theory, even though He/She/It is not specifically referenced. I had an astronomy prof that that suggested a supreme being could have caused the "big bang."
However, theology is not science. As has been denmonstrated in this thread, people have different ideas of the universe's driving force. These should be confined to theology classes or the home.
I don't agree with the majority of your post but your conclusion is on the right track as long as you play it evenly on both sides. I mean think about it, do you believe it appropriate that taxpayer funded public schools should have the privilege of teaching their version of 'the process by which we came to be' when that process is in direct conflict with what the parent's theological beliefs are? Personally, I think that it's entirely possible to have a totally valid science class without invoking any discussion of either evolution or theology. I fail to see (at least for any schooling up to say the completion of high school) what it adds to the learning of science for the individual.
