This indicates that MacKenzie hasn't a clue as to what faith is. Blind acceptance has nothing to do with it. He might start by trying to gain some genuine understanding of the subject before going on about it. That's how sound thinking proceeds. MacKenzie's bland assumptions certainly seem to have compromised his ability to think critically.
MacKenzie ... feels that the blind acceptance necessary for faith might “compromise one’s ability to think critically, a key ingredient in scientific thinking”.
Update: Dave Lull sends along Faith and the Human Genome.
