Evolution is a difficult subject for religious conservatives for obvious reasons: it conflicts with a literal interpretation of the Bible. But even religious moderates can find evolution a distasteful subject: it infringes on some important attitudes towards human exceptionalism, as well as religious beliefs about the importance of a personal God. Many religious progressives, on the other hand, rejecting biblical literalism and human exceptionalism, and holding a personal God, simplistically understood, to be less important to their theology, often embrace evolution.
