Can you imagine all the major world religions come together to build greater world peace and bahai walk away because he feels everyone should follow the promised one in order to do so? (or a christian, christ etc)
I mean JW offers me Watchtowers when they can. Catholics want me to come back to church after giving me a fifth rosary. Im sure there be more o offering without door to door evangelizing or another inquisition.
Bottom line is that 'my way or the highway' simply doesn't work. Too many people take the highway, and run away. Many groups refuse to participate in interfaith discussion, because of all kinds of reasons, like the notion that the other people there will somehow corrupt them, but also more commonly because 'we're above that.
For me personally, and with the training/teachings we have, for a more accurate assessment, we practice 'be the watcher' and even though we're part of the debate, we have to take a step back occasionally, and view it as if we were in the audience, and a neutral participant. This brings, in my opinion, a much more rounded perspective.
People who cling to the infallible prophet faiths must need that. it provides security, a safe haven away from too much distraction, like minded company, and more. In other words, it perfectly meets the needs of individuals needing that type of situation. Just because it doesn't work for me, doesn't mean it doesn't work for them. Obviously it does.
But somewhere in growth there is a jump over to 'oh oh, maybe not everyone perceives things this way.' I'm not sure what causes that jump, and it is a big one. On a personal note, I took a 10-15 year hiatus from Hindu practices, Hindu philosophy, and more. Guess what? it wasn't the end of the world. We enjoyed ourselves in ways we couldn't have otherwise. But most of all, it made us realise that it really was for us. It suits us.
As the saying goes, 'When the going gets tough, the tough get going."
