See the funny thing goin on.
I think, here, discussants write and debate without reading what is already available in the allempires.com on Dravidians.
I do not want to repeat.
The non-Indians have confused themselves about caste and varna and so also race and language.
In the so-called "Aryan Ramayana", the Dravidian Mandothari repeatedly call her husband Dravidian Ravana "Arya", "Aryaputra" and so on. Had the Dravidians been so conscious, they should have called themselves so.
Take the case of "Brahui" language and IVC of "Dravidians".
Had the Dravidians been there, the Sangam literature atleast should mention about it. But it goes no talks about Himalayas, Ganges, Nandas, Mauryas, Meru, and so on.
The study of "Sangam literature" considered as the extant of literature of the "Dravidians" bring out the facts.
As already pointed out, it mentions about "Aryans" seven times, but none about themselves.
