The article quotes the usual silly commentators who are intentionally out of touch with reality such as Sam Heilmann, Michael Saloman and Chananya Weisman. They should tell you how much intentional fictional information is included.
And based on the comments to the articles about the Mormons, it seems that the sources for information about them are similarly intent on prevarication.
So it may be an interesting article but you must consider that it, for a very large part, is based on the information provided by people with the specific intent of painting those communities in a bad light by way of prevarication.
