Quick question: does the "The peasants are unhappy that the local Lord does not follow the majority religion" appear if the majority religion is paganism? I think it would make sense that it does, even when the Lord is also pagan: after all, if it's not organized, it's probably not the same brand of paganism.
I do not believe it does. As I said in a previous post, that would be a possibility. But it should probably not be as strong as the current effect. If the local lord is a pagan, it's completely possible that he follows some of the local beliefs.
