"Sometimes people have said that Islam, in its own calendar, is still only in the Middle Ages. It's still in the fifteenth century or whatever. And Christianity in the fifteenth century, after all, was full of inquisitions and burnings at the stake, and so on and so on. So give Islam time, and it will reach the point of maturity that other religions have. But Mormonism is much younger than Islam, and it's got there already. So I don't think that's an argument that works."
