If your real goal is to free people from this cult, you might want to
consider that you lose ground and discredit yourself if you attack
the concept of there even being a God. Why not resist that temptation
to go straight for the Atheist evangilizing and try to say someting they
they might be actually able to hear, like the deceptive history of their doctrines,
and the failed prophesy and the concept of the governing body and
the several "classes" the Watchtower invented and the current sexual abuse cases.
Why do you suppose this is what most JWs want to listen to? In my experience, I have had a lot more traction with JWs when I discussed general issues regarding God and the reliability of the bible than when I discussed the org.
Simply put, it seem an attack at the org (or the GB) is something that plainly label you an apostate while questions which has to do with the bible is not taken personal the same way. Furthermore, any attack on the org/GB will immediately be answered by going to the bible and the question become if moses had an organization, what jesus really meant or if God will accept his appointed king to be impious in certain situations and so on. An atheist cannot honestly discuss those questions only from the bible because the bible is not what really inform his oppinion in these matters.
In my oppinion, one of the most annoying thing about religion is, when it want to be normative like the JWs, pretend to be interested in finding the truth through reason when it is really about confirming a particular set of beliefs. For an atheist to pretend he is interested in showing the JWs false by arguing religious doctrines when in reality his true reasons for dismissing their beliefs is that they, being based on the bible, should not be supposed to have any more truth than the harry potter books is in my oppinion no better in terms of honesty.
