I hear you Jeff, but.... Belief systems are built up over many years and do not change overnight. People defend belief systems against pain and even death - e.g. the soldier that dies on the battlefield under orders from his officer. You only change belief systems over time after exposure to new material that you start buying in to. It's a slow process. Your confrontation with Robert probably overwhelmed him and he defended his belief system. This does not mean Robert is the enemy. You need to show these guys the rabbit trail and they will probably start following it without feeling coerced by anyone. My 2 cents
