Just because they are out doesn't mean they don't still believe it.
I had a friend who was also DFed and we did hang out on occasion but her opinion was that she was litteraly commiting suicide by not getting reinstated.
So the people that won't talk to you probably feel like it would be adding to thier sins..
On the other hand I have had farily long conversations with people that were tecnically still in as far as I know.
