I didn't want to hijack the thread but reading:
http://www.jehovahs-witness.com/6/50019/1.ashx gave me an idea.
What are all the the ways that Witnesses are like other religions or organizations. That way when they come back with the reply that they are seperate from the world we can say say..."well not really when you look at it and here's why"
Some examples....
They say say that they are different because they go door to door...well don't the Mormons do that as well?
They say they are different because they don't celibrate Christmas...Arent there some eastern/pagan (or Jewish?) religions that don't follow suit with this as well?
Can you come up with any others?
