Quit calling creationism a theory. It isn't a theory. It does not have a single shred of evidence. People do believe it. So fuging what? Why should science teachers explain that some people believe in NON-scientific things in a SCIENCE class? You keep saying theory, Scot, and I don't think that word means what you think it means. Theory in science =/= layman's theory. If there were alternatives, those would be discussed. As it is, there aren't any, and there DAMN sure isn't one in creationism.
Why not tell kids in history class that some people believe the holocaust never happened? Why not tell kids that some people believe that blue is actually green and that yellow is actually red? Because that is exactly what you are positing with "why not say that some people don't believe it and believe in myths?" type of statements.
Already covered in prior posts.
Ridiculed is different than ignored. There are some undoubtedly who want them ridiculed but they are in the vast minority. Most simply want specific religious ideas ignored in science classes, or public school not specifically dedicated to religious discussions/topics. I don't think beliefs should be ridiculed in school but they also should be generally avoided, and science classes are absolutely not the place for religious belief systems.
It seems to me you are basically advocating what is already the case, mixed in with some lack of understanding apparently due to miseducation by some people in the past relating to the strength of evidence RE: creationism & ID.
More to do with a lot of what I see in news concerning the debate itself.
