> Meanwhile, why are people placing a harsh light on Mormons?
In most cases I would agree. For instance, knowing Clayton Christensen is a Mormon should have no impact on someone's opinion of disruption theory. And there are cases, like Mitt Romney, where the media placed way too much of a focus on his family being Mormon.
In this case though, the fact that the tycoon is Mormon plays a central role. His plans are literally based on drawings by Joseph Smith he found in researching mormon history. These are literally plans by the founder of Mormonism being implemented in the state where he was born (which is mentioned in the article as the reason why the tycoon is familiar with Vermont and thus chose it for his communities).
This isn't an article making fun of Mormons and "their sacred underwear" or other "let's point and laugh" material. It is an article about a man who studied Mormon history and decided to implement the vision of its founder. Mormonism is a key element to the story.
