Neve say never, I firmly believe there are many trapped in the BOrg that have their doubts. IMO it's not just what you try and teach them it's how you teach them, and searching for truly doubting ones.
Okay, that's a fair point. There are those who might (even subconsciously) wish that they didn't have to believe what they do, or wish that they didn't have to deny so much of modern science, and simply haven't heard the right information that can free them from their intellectual prison.
That's actually how it was for me. About ten years ago, I studied evolution and contrasted it with arguments for creationism (scientific ones, not the Society's limited attempts) because I wanted to get to the bottom of the matter once and for all. I didn't want to deny evolution if it was sufficiently proven. In the end, I didn't encounter any killer arguments in favor of evolution back then; I decided that the debate was a draw because each side could argue ad infinitum down to the smallest detail and a conclusion would never be reached.
Since then, I've learned about much more evidence, like our broken vitamin C gene, and ERVs that correspond with our simian relatives. But at one time, I wanted to know the truth but really just couldn't see enough evidence in favor of evolution to convince me to change sides.
I'm beginning to suspect that more and more creationists are quietly conceding victory (either subconsciously or otherwise); it's just gotten way too difficult to refute the evidence in favor of evolution without resorting to rhetoric, semantics, or plain old intellectual dishonesty.
To a degree, I might agree with you, but remember, it's not hard to refute evidence if you stop up your ears and sing "la la la". It doesn't matter how much evidence is piling up against your views if you are adept at ignoring it. We've seen on this very forum just how ignorant some creationists are about what evolution actually is, and how genes work, etc. So they were never playing on the same field as you were, by the same rules, to begin with. That's what makes it easy to keep believing in creationism.
