Oh, creationists wish there were objective moral truth. But they agree (wrongly) with postmodernists that there isn't really any objective moral truth. Hence their quoting the Dostoyevsky quote in their FAQ #4 above: "if God is dead then all things are lawful." Creationists fear that without God the Authority Figure to provide a morality for everyone to follow, everyone'll just go off half-cocked with their own self-serving belief system, and inevitably fight every other interest group that follows their own private system of "truths".
The real world provides us with plenty of objective consequences to good vs. bad behavior. Everyone gets to see a society's basic animating philosophies play themselves out over time. This gives us an objective framework by which to judge & learn.
I see Creationists as being in the third stage of grief: Magical thinking. They think that if only we can get everyone to believe in this one God - and this one conception of God - then we'll all be on the same moral page again, and society's headlong rush into nihilism (caused by accepting "materialistic" evolution as stated in #15) will be stopped.
They are the biggest champions of their version of absolute moral truth.
The Christian creationists on the Dover school board certainly weren't champions of absolute moral truth.
