In the end faith is a container that ensures protection of us one and all, only inside the container of true liberty, no matter where we are inside it.
Fringe thinking does not have to be rebellious thinking.
Was Marten Luther King and Mahatma Gandhi rebellious? I'd say yes, but they tried to bring about change through civil disobedience. Would they be allowed to do that if they were Baha'is?
To become a Baha'i' One would not to be a rabble-rouser.
I'm sure, that before joining the Baha'i Faith, some people were. But if a Baha'is stays within the "container", how "fringe" can they be? I'm talking about a person that has joined the Baha'i Faith but sees no problem drinking wine or beer once in a while... Or having casual sex now and then. And I wouldn't doubt that a few Baha'is are like that. You wouldn't want those types of people in high positions of leadership, would you? But, unless they were open about it, how would anybody know? I knew several Baha'is and not one was without some vice. So, who's going to be "perfect" enough to get voted in? And which vices are overlooked, while others are ignored?
Anyway, the Baha'i Faith is a little better than some of the other religions. There are a few safeguards to keep the Faith from getting taken over by the wrong people. But, since we're all just fallible people, even the ones we think are the "best" amongst us, might be hiding some secrets. Like some of those high-level people, like a Hand of the Cause, who wouldn't have that they'd have a lust for power and become a Covenant-Breaker?
