Yes it is. Joseph smith started the polygamy. He was the leader. Polygamy would have never happened if he didn’t give it the approval. They followed Joseph smiths teachings to a literal T. In fact Joseph smith has quotes on following the Bible to its literal meaning. He was a fundamentalist too. You are right about obey the laws of the land which is why it is odd that they waited so long after to do away with polygamy. as far as the church fighting the outlaw of polygamy in court I am not aware of. Where did you read this? I would like to know about it.
