Lets say a father has an adult child that wrote a DA letter. They are not living under the same roof anymore, so, working with the WT's teachings the father don't speak to the DAed person. But he still continues to see the child regularly, going to the movies, eating at restaurants and sitting besides each other at family barbecues and gatterings. In other words, doing everything like they used to be, only no talking involved.
Can this be cause for Disfellowshipping? Or can it be acceptable and seen as a matter of conscience.
