I think you're correct. I'm not Mormon, in fact I'm from an anti-Mormon family, but I do attend some Mormon services with a family member. This is in Michigan, far from Utah, so things may be tempered, but I see no evidence of abuse like this article describes.
FYI,watch the TV show “Escaping Polygamy”.
Highly entertaining as well as educational.
Probably available on U-tube, as is everything else.
