Its interesting how, when people such as Dawkins use comparitive symbolism, they always use a symbol of a basic material object that man can conceive...(a diamond or a teapot)
Dawkins seems to believe that freedom to reason and conclude is mans most precious resource. While stopping short of equating this with "ye shall be as gods..." I will point out that for believers, God pre-existed all human rationality, so we cannot imagine a teapot analogy.
I will agree that religion is a manipulative opiate, of sorts.
I will say that for believers, faith in an origin that is higher and grander than human wisdom can be a virtue...depending on the effects upon the life of that believer.
Dawkins strong atheism is a virtue as far as it goes...except when he tries to convert the masses. At least he believes strongly in something.
