That's one of the most interesting parts of human nature, IMO. People seem to have an innate ability to completely ignore certain aspects of reality that don't fit into their personal vision of the world. Often without even realizing they do it. You'd think Atheists would be less prone to it seeing as we deal with it almost every time we deal with theists but alas, that is simply not the case.
Blog #2 post was coherent, but didn't have a conclusive point. Then in the Science post #1 it was not defensible as laid out. It was really a question of who gives your free will because clearly every reaction of your life is laid out. It's similar to the thinking that "It was his time." It struck me as very dogmatic. Maybe it's the devolution of the conversation?
I just read two pages of the original blogs Roger posted. I originally smelled a fundie in his first post. Seeing what it leads to, I think that I'll attempt to dodge the poo pile that is that conversation. Poo Pile for me, gold to the next guy!
