I've really pretty much given up "debating" with anti's. What is absolute, naked truth to us is not to them.
It's like trying to debate religion. It's really a matter of a belief system and it doesn't HAVE to be logical. The only people who can prove that God exists with logic are the ones who believe it, anyway. Trying to prove through logic to a Christian that God does NOT exist isn't going to work because they already believe.
I had a little "debate" with some people on another forum recently. I laid out in very simple terms what my stance was and I was bombarded with demands for "proof". Proof? "What's that?", I asked. "Documentation", they said. "Whatever for?", I replied. "To prove your point", they said. I became a little frustrated at that point. I told them that I could cite author after author and web site after web site that agreed with me, but why would showing that people agreed with me validate my point? What am I going to do, cite information that DISagrees with me? Just because I can find published sources that agree with me doesn't prove that I am right nor would their citing of published sources that disagree with me invalidate my conclusions. I don't NEED to cite "proof", I realized. I believe what I believe and those beliefs are based on FACTS. I asked them that, if I revealed to them that I was a famous published author whose opinion they respected, would they then accept my stance? They replied that then it would be different. But would it? NOPE.
It just isn't worth debating stuff like that, anymore. I do it for kicks more than anything else. Very rarely will anyone ever be swayed.
