You know the problem I have with that poll is the wording. It implies that creationalism is a "Science". If you say Yes then you are agreeing that it is a science. Kind of made it hard for me.
I worded the poll, as a suggestion, and realized that that word to which you refer should probably be struck. But it was too late. The poll was up, almost instantly. In any event, with the word in, I would think it would reduce the vote for creationism/ID. It is clear that those that frequent this site, have views about what should be taught in science classes, that is tough to classify as science, by a margin of about 3-2. America is a land of deep religious faith, fundamentalist faith - an outlyier in the developed world, way out. Polls of Americans in general are only marginally different on this issue from those expressed on this site. We should remember that.
