William Lane Craig, Richard Dawkins, and the Moral Argument for God's Existence

Here's an interesting (and short!) video from William Lane Craig, in which he points out that Richard Dawkins seems to agree with both premises of the Moral Argument for God's Existence, while denying its conclusion. Craig's Moral Argument runs as follows:

1. If God does not exist, then objective moral values and duties do not exist.
2. Objective moral values and duties exist.
3. Therefore, God exists.

In his writings, Dawkins seems to understand that, without God, there is no objective good or evil (thus granting premise 1). Yet Dawkins goes on to condemn behavior that he regards as immoral (thus granting premise 2). Dawkins's denial of God's existence therefore shows that he is positively irrational.
