well, you'll be familiar with the genius idea of the 'selfish gene'.. and if there's no objective morality what is stopping someone who believes in that kind of materialist theology coming along and encouraging all men to be serial rapists?
remember, if there's no objective morality, that system is exactly equally as 'good' as any other.
"Objective morality" is a non starter. "Do no unnessary harm", pretty much sums it up.
If you read Dawkins, you must have been either genuinely interested in learning something from him, or you read it merely to critique. Not sure which. He is a scientist, and as such, he makes claims which are scientific, not emotion laden, and not tongue-in-cheek. The "selfish gene" is an hypothesis that deserves some investigation, in a scientific manner. You need to study some psychology or sociology. People are interested in this sort of thing in these fields.
Dawkins is not some stupid fellow that does not understand human nature, nor are you I suspect.
So let's quit this BS of the straw man arguments. It has all been tried before and never works. What really roils me is when you use "serial rapist" as if it is something that all men would be if they "but had the opportunity". This is insanity, and frankly, if you are in that boat, I am glad for you that religion is keeping you from carrying out this fantasy.
Personally, I don't need a god to keep me from senselessly harming others. Can you honestly say the same?
Much of what you say is laden with sarcasm and perhaps your take on "wittiness", such as "genius idea", etc. This is not witty. It means you don't understand what Dawkins meant at all. Such prose gets in the way of taking what you say seriously.
