Quarterback - Actually he wasn't a young man. You didn't read the OP.
He didn't become a JW until he was in his 40s. He was left in no doubt that there was a mountain of evidence for evolution that he had never considered. He was challenged for his intellectual dishonesty for promoting creationism without ever reading a single book that presents the facts for evolution. (did this touch a raw nerve with you?)
He now knows that Rom.1:20 cannot be reconciled with both theism and reality.
He now understands that equating evolution with moral nihilism is a fallacy.
He acknowledged to a total stranger his concerns over changes and failures of the organisation.
He heard a concise and powerful refutation of the blood dogma.
His confidence in his worldview has been significantly challenged. In future it might make a difference.
Isn't it strange that the one piece of superstition that JWs most commonly retain after leaving the cult is creationism? It is the one doctrine that is most easily disproved by objective evidence...
