Let's face it, the vast majority of the creationist movement is in the United States, so I think making the "un-American" statement is well justified.
So to the creationists, please, I'm begging you, please just show a little bit of modesty and give this fight up. You are doing no good by trying to push your particular brand of The Truth. The United States has been a global leader in sciences and technologies for the past hundred years or so, and yet you want to take this country that has given so much to the world and turn it into a place that scorns innovation.
Yes you think you're doing good by trying to get creationism or "intelligent design" or whatever into classrooms, but you're not. By teaching this particular "controversy" you're doing nothing but hurting yourselves. You think evolutionary theory and biology are threatening to your religion, but the real problem is that you can't see the forest for the trees. If you are successful in getting creationism into classrooms you will do nothing but destroy any chances future generations of American children have in the global marketplace.
You think people losing low-paying jobs to immigrants is bad? Just wait until you have to start importing scientists and engineers because the natives are receiving an education sub-standard to the rest of the world.
You lot have your own quaint little view of the world, how you think it was created, but the fact of the matter is that world view does not pay the bills; it doesn't create the medicine; it doesn't help the economy; it doesn't do anything but feed your own hubris. So for the good of the other 60% of the population and the rest of the world at large, just swallow your pride and go with whatever actually works (hint: it's not creationism)
