I must say, you're still missing ned's point.
let's spell it out in absolutely clear terms.
You are not prepared to discuss the bible with people who have never read the bible, who have little and most likely wrong knowledge about it.
We are not prepared to discuss evolution with people who have never seriously studied it (say, by reading a college level evo. bio text or taking such a class), who have little and most likely wrong knowledge about evolution.
And yet, who is it who comes barging in with the latest proof that will destroy evolution (aside from ray, that is)? The very same creos who are not predisposed to discuss the bible with "biblically" ignorant people.
The point is: if knowledge pertaining to a subject is required to discuss it, why do creos discuss that which they have no real knowledge of?
The irony kills.
