What kind of "conversation" would you like me to have with those who insist that The Judeo-Christian God says it's okay to worship idols?
I don't remember seeing anyone advocating the worship of idols. In case you are referring to me, I already explained to you that in the Baha'i faith, there is no idolatry. (Even less idolatry than among Christians, such as Catholics who sometimes seem to worship Jesus statues or pictures of saints -- no offense intended.)
What probably confused you was my explanation of the Baha'i stance that Hinduism is a divine religion by the same, single one God too. And many Hindus are known for idolatry.
So what is the answer? I gave it already: Krishna, a holy person for Hindus, was a divine prophet according to Baha'i theology. But that does not mean that all stories that were passed on about him, or the way the Hindu religion is often practized, is true to his real message. Over the many centuries and millennias, Hindu priests added many things to their scriptures, and many Hindus mixed Krishna's divine message with other traditions or believes. That's why many Hindus apparently commit idolatry -- although, if I am correctly informed, these idols are just symbols for the invisible Gods they worship, much like the Jesus statue is just a symbol for Catholics.
Another possible explanation is the following: We Baha'i believe in "progressive revelation", which means God "updates" the true religion every couple of centuries. That's necessary, because mankind develops and our ills change over time. God's divine message to Krishna, who revealed the Hindu religion, was the best cure for the illnesses of the Indian people at that time, and it was the best thing they were able to understand. Later, Christ came for another "update", finally Baha'u'llah.
And when you're dealing with an ancient society that's not very developed intellectually -- how do you proceed? Will you teach them the entire truth at once? No. That's why, for example, Moses did not reveal Jesus' message yet. In Moses' time, another message was more important. Likewise, Abraham did not reveal Moses' message yet. In Abraham's time, man was not capable of understanding it yet. When you teach first graders in elementary school, you will not start with college mathematics, right?
So maybe the Hindu faith was different, because man was not yet capable of understanding any more complex message yet. That's why later prophets "updated" the message, once man was capable of understanding it.
Baha'is believe Baha'u'llah is the most recent divine prophet. He condemned idolatry. That's why we don't do it, even if there exists idolatry in previous revelations. For us, the word of the most recent prophet, Baha'u'llah, is binding -- which means there is much truth in the other revelations, but they are "outdated versions".
