Where do I begin? How about this? I reject your definition of Cognitive Dissonance.
C.D. is the act of holding two mutually exclusive concepts or statements as true, although both cannot be true.
Wrong. C.D. is the uncomfortable feeling caused by holding two contradictory ideas simultaneously.
It is that uncomfortableness that is important because the Dissonance occurs when a person perceives a logical inconsistency among his or her cognitions. Dissonance is a problem that must be reduced or eliminated. That's done by ignoring or dismissing a thought or action. The average JW spends no time whatsoever thinking about how they might be rejecting the emblems, thus rejecting Christ. They just think it's an important observance and they are there to observe. An outsider might catch that problem, but the JW will just say that he "observed."
The JW does feel that he is outside of the New Covenant because they were told that it is for the "anointed." That is about the end of that because most people don't truly think deeper than what they were taught. They think their sins are forgiven on the basis of Jesus' blood being given to all who believe and accept the notion- not that actual blood (wine) into their mouth. It is not C.D. because they have already eliminated the dissonance long ago. It's gone.
Now, on to the word, atheist. I don't think it's atheists who claim no belief (without belief). It's monotheists who insist that atheists are without a belief. All atheists are saying is that they do not believe there is a god. That's it. Beyond that, the individuals have various beliefs according to what they have heard, read, observed, etc. Some see the possibility of foreign beings starting life on earth and some see the possibility of evolution starting in the primordial (sp) soup. Atheists are allowed to have beliefs and it's only closed-minded individuals like Perry that insist we are trying to say we have no beliefs. And there may be some who believe in God but use the tight exact definition that you apply and insist that they are simply "without God." Generalizations don't fit people when they decide on their own what they are and what it means. Society has given us labels and many of us try to make the labels fit the best we can. I am actually a rationalist- I will analyze and accept what is rational. But saying that, people will automatically put the atheist label on me, so I don't fight it. It's all just semantics. You even admit that "atheists" imagine a different definition than that found in dictionaries, so what's the big deal.
The stuff you say about believing his job will be there and employment- what are you smoking? It makes no sense. No comments.
You say " Unfortunately, many who leave, take their cognitive dissonance “skills” with them and become atheists. "
So I can say that many take their cognitive dissonance "skills" with them and dismiss the inconsistencies of the Bible and find a comfort zone in some other Christian religion. You can make a claim like yours all you want. That's just meaningless words.
You say, " Likewise, atheists should be proud of who they are. Instead of falsely portraying themselves as poor battered, misunderstood skeptics without belief, without a world-view, yea, without a religion of sorts; they should be promoting the glorious wonders of atheism."
That's not so, again you generalize. If we "promote the glorious wonders of atheism" we receive criticism like yours. Some do, some don't. Many of us just want to be left in peace. You have to take your own spiritual path. If you want to believe in a Sky Daddy who never did anything, who am I to say you should not?
You say, " The fact of the matter is that atheists have adopted a looking-glass lense that requires them to interpret phenonma incorrectly so that their precious world-view is not disturbed. "
I say the opposite, but that's when arguments start, so just leave atheists in peace. Why do assert that as "fact" ? It is clearly a fact that there is no conclusive proof of a God, but plenty of subjective proof of things that a Creationist/Bible-believer is wrong. In the end, you will say that I am ignoring proof and I will say that you are ignoring proof. Have a good day.
