There are so many recent joiners to this forum and many have the same questions about helping their loved one leave Jehovah's Witnesses.
We can try to cushion our statements. We can approach the subject with thinking questions that seem to be disconnected to JW issues, but really are not disconnected. We can state so-called "apostate" positions from a "doubter" view instead of one that is convinced of the lies.
We can learn all there is to learn about cognitive dissonance and dangerous mind-control cults.
We can read all kinds of things about JW history and doctrine and secret practises of the organization.
We can and should do what we can from the above to help someone we care about to free themself from the Jehovah's Witnesses.
But many of you newbies (and still a bunch of us oldbies here) want to know how to politely say
"Spouse/Parent/Sibling/Loved one, you have been wasting your life in a false belief system."
You must understand that crossing into that statement made to a JW loved one is the equivalent of saying "I am an apostate and I want to die at Armageddon. Further, I want to take you with me."
My wife used to literally put her hands on her ears (but did not say "LA LA LA LA, I can't hear you."). I had to learn to just move toward freedom without her and continually challenge her way of belief indirectly by finding seemingly unrelated things in the news and the entertainment programs we view. I had to dip, just occasionally, into interupting her disgust with something she hears about Babylon the Great or treatment of women or whatever, and remind her that Jehovah's Witnesses do the same or similar.
Don't stop posting your questions. Just understand that it has been heard before and people are not "insulting" you with their radical suggestions, and even when they are occasionally going too far in suggesting things about you or your loved ones, it is not meant as the insult they might present, but it is a comment from their own frustration.
So pose your questions here on JWN, and understand that others have answers for their situations that worked or did not work, but it may turn out different in your case. Post your thoughts on what did or did not work for you, or what you are currently trying.
