Presbyterians, typically one of the "regular Christian" denominations, adapt their beliefs to the truths of science, seeing science itself as a creation of God and therefore accurate.
With the recent fusion of modern right-wing politics with the mass media as well as with Christian fundamentalists and biblical literalists, some non-Christians view any denomination of Christian as little different from such a person.
Generally-speaking, it is a polarization of how Christians are being increasingly generally viewed; such thought is not without merit -- it is backed up in (one of) Richard Dawkins' books (he mostly writes about biology), "The God Delusion," in which he argues that liberal Christians inadvertently provide cover for fundamentalist, biblical literalist Christians to better perform their misdeeds with impunity, as they use the same language when talking about Jesus and God, yet can mean very different things, and that they are not doing enough to differentiate themselves.
