Hi awakening, Have you tried to just ask JWs simple questions like Billy the Ex-Bethelite did in his thread exJW Psychology 102--How to Ask a Question When Questions Aren't Allowed? I know that asking simple questions to help a JW's authentic persona to confront his cult persona is difficult - not impossible. It will get easier with practise and is easier than trying to convince JWs that they are wrong.
When you feel frustrated with telling JWs that they are wrong, look in the mirror and remember what Einstein said, "Insanity: doing the same thing over and over again and expecting different results. - Albert Einstein". Then ask yourself, "Who is insane for debatting with a JW?", and try doing something different.
Peace be with you and everyone, who you love,
Robert
