I have experienced similar. I have never even been talked to by the elders. We have elected to 'fade out' if they let us. I had a 'sister' stand 3 feet away in a coffee shop for 10 minutes and refuse to even acknowledge my presence.
I wonder - since gossip is a disfellowshipping offense - how she found out I had 'apostate' thinking anyway? Certainly the Pharassies would not have said anything to her?
I have determined that the next time it happens I will make a scene. I will let everyone in the area know that this rude person is a witness, and how shocked I am at the treatment. That should make a little trouble for the next dub to the door - !
