I totally agree that they are choosing to shun. People have refused to hurt or give away their families under pain of terrible torture. Following orders is no excuse.
Sometimes they won't discuss what they are doing and just expect us to accept our 'punishment'. When they do this, as my family have done, then I think it's time to break ties.
There are consequences to hurting people. They have to accept these consequences or at the very least we have to show them that they don't get away with cruelty. Being normal and reacting normally to appalling treatment is hopefully the way to reach their authentic self, if that is still possible.
