Have to agree with Talesin on this one.
The only time my Mom ever saw my Dad cry was when they heard my gay brother was being DFed. It was excruciating for my parents, but they shunned my brother out of (twisted) love for God and (twisted) love for my brother.
It was also my personal shunning of my brother that finally broke through my Cognitive Dissonance and started me down the path to awakening.
To be fair, I get your point. Shunning is non-action. But, for most, it is not without great pain.
