Somehow I misread your question as "what do you think of
his views on religion", when you really asked what his views are
He states that on a scale from one to seven, where one is complete faith that god exist, and seven is complete faith that god does not exists, he's a six-and-a-half: He cannot prove
that god doesn't exist, so absolute disbelief in him wouldn't make sense. But neither could you prove that witches, fairly, and unicorns don't exist, and we generally agree that they don't exist, because there is no evidence for him. Dawkins considers the existence of god(s) about as likely as the existence of unicorns.
Dawkins considers religions to be collective delusions, in the same sense as someone who thinks he's Napoleon is under an individual delusion.
As I said, I agree with all that.
