On the FDS question, I think I would play dumb about it and insist that they prove to you that it is a class. Even if it was a class, they would still need to prove that it was their organization that had been selected as the class, and their lies, false prophecies and corruption make it obvious that God would never use an organization like that as His spokesman.
Also, when we consider the way they treat members who dare to disagree with any doctrinal point, they appear to be much closer to fitting the description of the "evil slave" who 'beats his brothers' than to the "faithful and discreet slave".
On the topic of getting out of Babylon the Great, I think that, again, you should make them prove to you that BTG means ALL false religion through all of history, and not a specific organization existing at a specific time. In prophetic areas, the JW's really can't prove anything biblically. The basis for their explanations of prophecy is "because that's what the Watchtower says it means." Take away the common ground underlying that assumption, and they can't prove a thing.
And where should you go when you leave false religion? Not to an organization, but to a Person. Jesus Christ said, "I am the way, the truth and the life. No one comes to the Father except through me." No organization necessary.
