Why Do Christians Want a Craig-Dawkins Debate, But Not One With Me?

Although not all Christians say this, some do. Isn't that disingenuous? Surely if they want to see Craig trash Dawkins in a debate then they have no qualms about seeing such a thing, if that should happen with me. Consistency thou art a jewel! They may have other reasons but to say he will trash me cannot be one of them.
