I found this extremely uncomfortable to watch.
Robbie was told :This is not a court of law" That became all too apparent. He would have received less harsh treatment in a "worldly" court. The elder said that they must all be convinced of his repentance in order to show mercy. Isn't this entirely the wrong way round? Law courts have the responsibility to establish guilt beyond all reasonable doubt to return a guilty verdict.
Their creepy, pseudo-gentle demeanour cannot fool anyone. This organisation is cruel, self righteous and judgemental.
