== PBS Frontline == 

 There was a PBS Frontline special on the Mosuo people. On the Frontline website, the statement is there. PBS is a reputable source, and certainly a documentary on the Mosuo people can give more insight to their culture. Simply saying that you're suspicious doesn't guarantee proof. Have you studied their language? Certainly, I am sure that they have learned of the words for murder, war, and rape from Mandarin Chinese, but Chinese languages and dialects remain strongly unique, and picking up words here and there does not generally happen. Regions and their people remain very proud and firmly rooted in their own culture, dialect/language.
