I don't see a need, whereas I think you do. For me the need is just tolerance. I know enough about Bahai to know its non-violent. That's enough. Other than intellectual knowledge, I just have no need at all to dig into Bahai belief. So its a case of, 'if you leave me alone. I'll leave you alone.' From this forum I've learned that individual bahais have differing focuses. Of the three I've read quite a bit about, one is here to present information about Bahai, another was here to argue and proselytize, and then there's you, who is just more curious about the world in general. Hopefully you've learned similarly about Hinduism ... that we're a varied lot.
Of course if anybody wants to understand any other religion, they can go exploring, via books, by entering houses of worship, etc.
