Isn't that a little overly dramatic? Maybe you weren't aware of it but textbooks and curricula are rewritten and replaced every now and again.
Like many (indeed it often seems all) evolution critics, you are implicitly confusing curricula, which merely reports about and reflects the state of scientific theory and knowledge, with science itself.
No ruling about curricula can effect science, any more than a sports writer misreporting the outcome of a baseball game can change what happened on the diamond.
The gavel never comes down on science. You can always change the content of science. All you need to do is come up with a better theory. But you can only (honestly) include in the curricula those ideas that have first and actually succeeded as science.
I appreciate your response, stultis, and good points. You've always been a good person to discuss things with.
