"His views" go well beyond denying evolution. He takes a literal view of the Bible and would probably like to see us all living by it. He has demonstrated illiberal views on abortion. His eyes are shut to solid scientific evidence and wide open to quackery of the worst kind. On his own he is just a silly and deluded man. But he isn't on his own. His spirit is shared by a fair number of charismatic fundamentalists (not only Christians, either) whose certainties have convinced them that it's right to foist their views forcibly on others and to deny good science. Witness attempts to get equal billing for creationism with evolution in schools, or, worse still, to prevent the teaching of evolution altogether. Now if you think that a world significantly influenced by people like that wouldn't be less civilised even than the one we have now, well I'm not with you.
