So Mormons, basically.
They are doing a hell of a lot better job than most Whites.
Yes they are, and they are Christian, and they breed, and they are rather White. Ever wonder why there are things like "Big Love" and "Book of Mormon?" Now you know. Can't have people getting interested in that! Okay, maybe you think their church is weird, but the Mormons I've worked with and lived near were solid people, if a bit exclusionary. But hey, are we really going to argue that the Mormon Church needs to be more inclusive of non Mormons here?
I was once told by a Jewish guy of the historical symbiosis between Jews and Mormons in USA both being disfavored groups. That's off the table today, goys.
