:: The concept of Aryan and Dravidian race is still controversial, especially when you regard particular communities as Dravidians and particular communities as non-Dravidian. Anyway, without dwelving into something about genetics which is unrelated to this article, there isn't another instance of the usage of the term "Dravidian politician" or "Dravidian social activist" anywhere in the project. Politicians from Dravidian parties are only mentioned as Tamil politicians. In Periyar's context, it is better to view the term "Dravidian" as a political term than use it in the racial context.-
