When I first started questioning WT, then the Bible, I discovered a video series on Youtube called, "The Atheist Experience". I was absolutely fascinated not only by their logic and sound reasoning, but mostly by how quickly and easily the atheists shredded the simple-minded arguments and beliefs of Christians.
I also realized that despite being a JW my entire life, I also had nagging doubts about the Bible I never had the freedom to entertain as a JW, but the atheists decimated those very same doubts with their reasoning.
In the end, while you may not come around to the other person's view, it is enlightening to learn why people believe what they do.
