Yes. Baha'is say there has been a progression of new and better knowledge and laws of God. That in each age people should leave their old religion and follow the new religion of God. But then, they also say that each message was suited specifically to a people, a place, and a time, So the many different messages weren't really meant for all people in all cultures. Then how is that a progression of "new" knowledge? Were the people in India supposed to get rid of their many Hindu beliefs and adopt the Laws of Moses? Then the religions that did spread across several places and did replace the old religions of the people were forced on the people... like Christianity and Islam. And, since Islam was newer, was it supposed to replace Christianity? For the Baha'is yes, because they say Christianity had gotten off track by making Jesus into a God. They say Islam "corrected" that false belief.
But that means that Christians should have converted to Islam on their own without being forced. They should have recognized the truth in Muhammad's teachings and adopted the new laws from God. So maybe the early Mormons were the only Christians that were close to being right. They had multiple wives just like God wanted people to have.
Or... it's absolutely nuts to think that anyone else but the people themselves made their own laws for their own culture, for the good and the bad. Then said, "The Gods have decreed these laws. And thou shalt obey or The Gods will punish you forever and ever after you die. Oh, and The Gods have also decreed that we are in power and have the right to kill you if you don't obey. Then... after we kill you, The Gods will punish you even more.... forever and ever."
