Delusion?

This past week I saw a short interview with Richard Dawkins. He is a British biologist and the author of the best selling The God Delusion (2006). He made the following statement, "Not all religious people are ignorant, but all ignorant people are religious". Not only did I find this statement arrogant and ignorant, but Dawkins is a great illustration of what Paul speaks of in 1 Corinthians 1:

For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God. For it is written, "I will destroy the wisdom of the wise, and the discernment of the discerning I will thwart." Where is the one who is wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe. For Jews demand signs and Greeks wisdom, but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. For the foolishness of God is wiser than men, and the weakness of God is stronger than men. (vv. 18-25)

So, then, who is truly deluded? Who is truly ignorant?
