I don't think anyone demonizes these people but I can't help to believe that these people over at answersingenesis Ken Ham and the like are good, competent people that happen to be fervently religious. I must say I deeply respect this.
To be more on topic,
when creationists say that creationism doesn't change I've thought they were simply referring to the Word of God. I was looking for a source to support this statement but I'm sure everyone here is well versed enough in articles where the "inerrant Word of God" has been referred to as unchanging. They obviously have to adapt their scientific arguments because science changes daily, all of the physical sciences do. Everytime there is a new find in anthropology (for example:
florensis), physics (string theory) and what not.
I checked out the site and they are proponents for logic and reasoning. Overall they're doing a lot more good than the televangelists and Hovind types. Anyone know where their "creation science museum" is based?
I must admit however that I am quite partial to creationism and Christian fundamentalism. I find beauty in it. Paulk sees a dishonesty in the movement of creationism overall but I see a honesty. With establishing a worldview that makes you something in rejection of evolution.
