Yes, Finkelstein, this is true with diehard members. The experience I have identified above have a blood is thicker than water policy. The WT does have some issues with their DF family members policy and that is why they constantly remind us to keep obeying this practice. There are many JW families that have children that would have been DF'd but they faded, and missed that crazy punishment.
In certain family circles, you can get away with saying anything and it is overlooked.
