SBF - I suspect you are not even sure that the Watchtower are wrong in any meaningful sense. You simply find their narrative to be less useful to you than you once did. Is this a fair characterisation?
Actually I would argue that I believe JWs are wrong in a more profound way than simply being factually wrong. It's your approach that leaves people theoretically vulnerable to return. The logic of your approach is that if evidence emerges that JW doctrines were in fact "true" then we should all go back and take part again. That's why I think ethical and aesthetic grounds for rejecting JW beliefs are often more compelling and satisfying than merely disagreements over scientific facts.
Since my rejection of JW ideology does not at its heart rely upon a refutation of its truth value, I am not vulnerable to counter-evidence as you are.
There was an excellent thread on the forum many years ago with a subject along the lines: "who else left JWs while still believing it was true?" Many people on the thread described the amazing process of rejecting the prospect of future paradise on earth, while believing it in full to be true, because they found life as a JW unbareable in the here and now.
