This documentary was shown on British TV a few weeks ago.
It did appear to be the case that as the girls grow, they are forming their own more educated opinions, and breaking away from the values of their mother. Newer songs written by them are more concerned with boyfriends and lost love and other standard teen fare, rather than racially motivated propaganda. When questioned outside their mothers aegis, the girls seemed very concerned about how they were percieved, and were not in agreement with certain racist values. Little things like the fact the girls had thrown away their nazi-smiley t-shirts, only for it to become apparent that their mother, without their knowledge, had kept them, suggest that it is not completely clear cut. Given a broader education and a reasonable upbringing, their is no reason to believe that these twins could not become decent members of society.
What is infintely more disturbing, is the nature of their relationship with an imprisoned white supremacist. Certain comments he made about the girls being "fantasy daughters, sisters and lovers" struck me as chilling in the extreme. The fact that their mother would countenance such behaviour .. sickening. Regardless of her beliefs about white supremacy, it seems almost unbelievable that a mother would allow this relationship to continue.
On the whole, I hope that grandma succeeds in getting custody, or that the girls strike out on their own.
