This actually happened to a friend of mine. We've all been in discussions with fundamentalists Christians at one time or another that have annoyed the heck out of us (if not, you have yet to live). My friend, who met this character on an airplane, came up with a very good, effective way to silence these narrow-minded boobs that I'm sure we all can learn from. He said all this with a completely straight face. Man on the plane: "Soooooooo... what church do YOU go to?" My friend: "Well, [long pause here]...I'm a Druid." Man: "I beg your pardon?" Friend: "We worship trees." Man (after a pause): "Oh, ..." After this, the man seemed a little disappointed, so my friend added: "If YOU were from Amarillo, you'd worship trees, too!" [Note: Amarillo, Texas, in the heart of the Bible Belt, is known for its completely featureless, flat, boring landscape.]
