It is interesting that you think something at odds with JW teaches and keep quiet about it there are no repercussion. Eventually this will become an issue with them. You will send your child to college, have that blood transfusion or they interfere with your family life.
We all have family or friends in the delusion, and would love to be able to talk with them freely about anything. It can't happen.
There are several similar religions ( Amish, Islam; and Scientology; their teachings are so different but just as damaging to the membership.) Islam will "take care" of the dissenter personally. JWs will just treat you as if you are dead,
