Um.. no? They rape little girls and force boys out of their homes (because the older men want as many women/girls as they can). They also traded these women around with other men like cattle. These people are not sin free.. the men live a very hedonistic lifestyle and the women allow themselves to be abused.
I fail to see how forcing your daughters to be raped by 50 year old men and kicking your boys out of your community so those same men can have more sex equates to wonderful family values.
