No, it's anti-CREATIONIST bias. Some Christians are creationists, and some are not.
One of the interesting things is that creationists have just about the same entrenched attitude with evolutionist Christians as they do with science. The creationists are always right, and everyone else is wrong, even if they're another Christian.
I was on that side of the fence for perhaps a year on these threads, so I know of where I speak.
