cantleave - you may be literally "correct" - but your, ahem, method of communicating your correctness lacks empathy and is off-putting.
Similarly, Judge Rutherford made many "correct" comments about "Christendom's" hypocrisy - but his method of communicating - highly disrespectful, aggressive and sarcastic - got in the way of the perfectly good points he tried to convey. Exposure without respect often creates more heat than light.
Sometimes a little understanding and less harsh judgement work wonders. It gives people space to carefully consider your points without batting away unnecessary judgements.
I agree so much in principle with your comments about not supporting a delusional belief system. Yet in life sometimes we try to balance the need to be "correct" with the need to be "effective".
Up and completely leaving an organization regardless of commitments and relationships may not be the most effective in terms of getting a better result in terms of your personal goals for family and friends. For example, a close friend of mine realized several years ago the organization was not all it claimed to be but his wife was a born-in witness who would have baulked at any move on his part to leave. Gradually over the years he was able to share a few of his misgivings and slowly she could digest what he was saying and she became less reactive. Fact is, if he had left immediately, she would never have given him the time - or respectful listening ear - and he stood a chance of losing a perfectly loving spouse.
Life is not all about "correctness"; it also includes compassion and - here's the main point I'm making - planning ahead so that your outcomes have a greater likelihood of getting the results that are so imporant to you.
