I can't find the thread now, but I posted "Have you ever talked to Jehovah's Witnesses" on ship-of-fools.com. The responses showed that maybe 40% had never even spoken to them, though most had at least heard of them. There were a few comments along the lines of "nice people", plenty of "they aren't Christians", and some that felt a need to de-convert them when they come to the door.
JW's are a legend in their own mind, but not in the world at large. (Surprise, surprise, eh?)
GREAT topic, LadyLee!
