@logical1, very great logic, indeed! I commend your rational thinking. But, I can assure you, from bitter personal experience, your sharpest sword wouldn't even cut butter with most of the JWs. I can be a very cunning debater, and people say I give the best saleman pitch anytime I wish to pass a message (at least, my university professors tell me so), yet I have tried most of these arguments with JWs all around me, save the infinite argument, but I doubt even that would work, you know why? Because the cognitive dissonance of an average JW is raised to the power of exponential infinite!
But yes, maybe, it could strike a cord somewhere down down their minds, so I commend you once again- powerful arguments you've got!
