Hiemere, I appreciate your overall theme--that believing we've found absolute truth, or that it's even possible to find it--likely isn't possible, but I do have a couple points of contention.
Why do Witnesses and some ex-Witnesses have this obsession with finding "the truth"? Nobody else has it.
I think there are many groups that have this obsession with finding absolute truth and think they've found it. You're describing pretty much every fundamentalist group in history. Groups like Westboro are outliers in how vocal and shamelessly offensive they are in proclaiming "the truth," not in thinking they've found it.
And to speak up for team atheist a bit... I know you weren't saying this, but I want to clarify that, while atheists can be vocal and strident, they don't claim to have found any absolute truth. In fact, I don't see any other group who are nearly as vocal in saying that knowledge is provisional.
I mean, if you were one who thought the religion of JWs was the truth, you don't have the best track record proving you can find and tell if you have "the truth" or not. "I was in a cult for several years and believed it was the truth, but now that I'm out, I'm a good judge of knowing what is true and not." I'm sorry, but how did you suddenly gain the capacity to judge such things objectively when you once failed at it so miserably?
This seems a pretty unfair ad hominem. Many (most) JWs were raised in their religion, and were never taught to think logically--in fact, were taught the opposite. This kind of mis-education from infancy can be extremely difficult to overcome. I think a case could be made that those who were able to overcome their brainwashing (and immense social pressures) actually show exceptional logical thinking abilities, since they had such a deep hole to climb out of.
