There's a difference though when you try to make creationism/ID part of school cirricula as part of your agenda. Certainly, they are entitled to their own opinion. But science isn't a democratic process - what is or what isn't accurate is decided by research, not by vote. And the research points towards evolution.
Evols were even upset when one school system wanted to put a sticker on their science books that said "Evolution is a theory." Sounds like evols have their own agenda, e.g. don't question the party line.
