I gave up trying to tell JWs (who are content) that all is not right in their religion. I only wanted them to know why I don't go anymore.
Many JWs cling to the religion because their whole life revolves around it and they know nothing else. They will justify staying there no matter how many scandals there are. Besides, if they are old, they cannot start over. It's really too late (some might disagree). It's almost too cruel UNLESS you can give them an identical community that can provide them with everything the JW religion supposedly provides them with. You can't. So, let them stay there.
So, I don't bother and don't feel the need to expose the JW religion unless I am honestly and directly asked by some "friend" who I suspect has doubts about it all. And I will warn them first that they will not like what I have to say. If they say "tell me" then I will.
Generally speaking, Witnesses do not care and are not interested in hearing anything that will upset their fantasy. You will only be accused of trying to "rob" them of their faith, which I have no interest in doing.
I am just glad that I'M out and have no family there.
