EITHER God exists, OR the theory of evolution is true.
I know, through divine revelation that God exists, therefore the theory of evolution is false.
They prefer not to consider the effect of their XOR premise on those who find the evidence for evolution compelling.
Indeed. Richard Dawkins is a good example of a person who has chosen the other side of the same conclusion: "Either God exists, or the theory of evolution is true. Evolution is true, therefore God does not exist." Funny how they agree on the initial premise, isn't it? ;)
