I just finished reading when men become Gods: Mormon Polygamist Warren Jeffs, his cult of fear, and the women who fought back.
If you want to know more about the FLDS this is a great read.
The fact of the matter is that I find it very hard to believe that the FLDS has been getting away with as much as they have for so long. The underage marriage part really disgusts me. And now that I know they hate American I'm curious as to why they continue to live here.
