So how does your faith community deal with dissidents? Those who are aligned to your community yet openly disparage its core beliefs? How about those who exploit others sexually and financially? Do you let it slide because you are enlightened and above all this medieval behaviour of the Baha'is?
Hindu faith communities are a varied lot, and I'm not privy to how organisations deal with it when it comes up. Sadness, denial, I suppose. One swami in Texas was charged with sexual impropriety and he fled the country. So the legal authorities in the US have a warrant out to arrest him if he returns. Certainly close devotees might back their guy, and no doubt that could be poor judgement.
The temple groups are different. They run temples, and nothing else. If someone breaks the law (there was priest in a temple in British Columbia charged) it goes to the legal system, unless the guy runs. There is no 'core belief' as you put it in temple societies. Vedantins, monists, pluralists, traditionalists, liberals, they all worship together.
My personal monistic Saiva Siddhanta organisation is really hard to get into, so that in itself is a precaution.
So that stuff happens in all faiths.
