CC and Jess have been continuing the discussion of the theist/atheist divide that started with the infamous ad in the latest UUWorld. I think the other subject du jour, the healthcare debate, can illustrate the point CC and I have been trying to make for years (only she usually does it more eloquently)
When you see a sign or poster with President Obama painted like The Joker, or calling him a fascist, are you convinced? Do you want to break bread with someone carrying a placard depicting Obama with a toothbrush moustache?
Then why do think I'll be convinced by a sign quoting Dawkins? Why would you think I'd listen to any argument that begins with "Faith is believing what you know ain't so"?
