A non-believer can demonstrate that the WTS is incorrect in many of its Biblical interpretations by using the Bible itself to prove this. The non-believer can then go on to prove the Bible itself to be suspect, at least as the literal word of God, by providing external evidence for this fact.
Indeed the "non-believer" can proceed on that basis. But "non-believer" as I understand the terms does not equate with someone who claims belief in nothing as I have tried to sketch. A non-believer is typically someone who affirms all sorts of commonplace secular assumptions such as the primacy of rationality, the reliability of the empirical method, the unliklihood of supernatural intervention and so on. This is not what I had in mind when I said someone who believes in nothing has difficulty articulating why they feel the Witnesses are wrong. To be a "non-believer" you must believe in all sorts of things, and as such have no problem rejecting the Witness view because it largely contradict those beliefs.
But how does someone who genuinely believes nothing reject Jehovah's Witnesses and all the while make sense, that is my question. On the other hand, maybe it does not make sense to make the claim "I believe in nothing" at all.
