I thought creationism was the belief that man and dinosaurs lived together and that the world is only a few thousand years old.
Ahem....NOT ALL CREATONISTS BELIEVE THE EARTH IS ONLY 6,000 YEARS OLD. Evolutionists need to get that idea out of their head. There is nothing in the Bible that states WHEN the Earth was created. Some guy, somewhere, worked backwards throught the genealogies listed in the Bible starting with the birth of Christ and calculated it based on the ages of the ancestors listed. It was strictly a human idea and I am not familiar, myself, with any denominations that teach it and require it to be believed. It is not part of the teaching of the Bible. (Sorry to yell at you.)
My gut feeling (derived from numerous debates with them) is that a majority on the creationist side in FR *DO* believe that the world is only 6000 years old. They see that as the only possible way of reading the Bible, and many appear to regard those who disagree with them in this as non-christian. Almost without exception these people have co-opted the term ID as describing their position (They think that makes their position sound more scientific; it doesn't). If you don't agree with that your argument is with them, not those on the mainstream science side of the debate.
Actually, it's ID apologists who've been pushing the party line that only YEC'ers are true creationists. It's the only way that ID'ers can hope to extricate themselves from the claim that they want to teach religion in science classes.
BTW, this is also why the Discovery Institute has stopped trying to get ID taught in schools. Now they want them to "teach our controversy" about evolution, but oh no, we don't want ID itself to be taught.
Clintonian-strength spin doctoring, but it has served them well in the PR sphere so far. (It's in the process of breaking down in the legal sphere, because they don't have a leg to stand on. But it's good enough to impress enough school boards that they should be able to keep the game running a long time yet.)
Aw, now ya gone and done it. Some YECer will go after you now.
It's too bad that an omnipotent God can't get all his believers believing the same thing.
