Well, I am not goint to stay, it simply to much of a waste of time, maybe I will check back in in a few years, and I would be happy to provide reading recommendations for anyone who asks me. (It would not be hard to find my real e-mail address using the information about me you already know). But I will take up this last discussion because of your specific invitation. 

The Tangut did not speak Chinese, they spoke their own language. The official name of their land in their own language has been written about by Ksenia Kepping and is available on a link from the Tangut Language page. In no case was Xia there autonym. It was something like Minyag which is waht they are called in Tibetan. 

In general I have a big chip on my sholder about Sinologists becomming confucian literati. The Yuan, and Qing were no more Chinese than I am. To use Chinese names for these political entities is to take for granted the medieval Chinese worldview. While now it is indeed true that the PRC owns a big chunk of Asia how much of it is actually historically China?

The Jurchen's, Kitans, Tangut, Mongols, Tibetans, Nanchao, Azha (Tüyühün) were their own countries with their own languages and customs. Tangut history is relevant to Chinese history in the way that French history is relevant to English history, but also vice versa. 

To have a thing on the article saying 'this article is part of the section Chinese History' reinforces the view that the Tangut's don't deserve their own history. 

There is a sociological fact about Western academia that Sinology is big and well funded, while Tangutology, Nanchaology, Kitanology etc. are all virtually nonexistant. But this is a fact about us, and not about the history of Central/East Asia.
