"Liberal theorists, like Rawls, say that unless we keep religious reasons out of the public sphere, we could descend into a religiously motivated civil war similar to the Thirty Years’ War of the sixteenth century. On the other hand, critics of liberal theorists, like religious ethicist Charles Mathewes, say that unless we allow each other to talk about our deep differences, such as our religious beliefs, we could descend into the same nightmare that concerns the liberal theorists. ... One of the premises of this entire debate is that religious people want to use religious reasons in public debates."
