It occurs to me, if I was starting from scratch choosing a religion or belief system to join, there's one good question I should like answered first:
Does this religion promote a way of life and view of the world that would be satisfying even if not a single word of its doctrines are true?
If JWs honestly answered that question I doubt many would say it's a good choice. Yet other religions and belief systems probably could pass that test. In fact I read a book, "Good and Bad Religion" by Peter Vardy, that encourages such a practical evaluation of religion on that basis. He asks whether the religion promotes freedom, creativity, compassion and so on. JWs must score very poorly on all these.

This approach to evaluating JWs and religion generally is much more productive that merely an evaluation of whether the doctrines are "true".
