Yes, I understand what you are saying. However, there are many devotees who entered Iskcon as teenagers and were for the most part raised by Iskcon. Iskcon has been their guardian, family, teacher, and basically their employer for the whole of their adult lives. They know nothing else but life in Iskcon.
Living such regulated lifes, since such a young age, they did not have the chance to develope the "common sense" that comes with experience and mistakes. It is a learning process. Also, being sheltered within the temples away from the hard knocks of working and living in the outside would tend to keep one a bit on the naive side.
These devotees gave their youth, energy, everything to Iskcon and Iskcon became everything to these devotees. Are they now to be shown the door as their elderly age, disease and fast approaching deaths render them useless and a burden in the eyes of the management?
