BRAHMINS are the Aryan. Mass people are the Dravidian. Thanks for clarifying that. Your information about the Dravidian is true for the surrendered portion of the Dravidian People, are the so called Lower classes(called by Animal Aryan).
But the Bangladeshi Nation is not surrendered Dravidian Nation. We maintained the freedom of the religion from the ancient time.
If, all the Dravidians know the true tragic history of the ancient Dravidian Nation, they must bounce back and must crush this small but cruel Aryan Cluster( Aggressor, came from Eastern Europe). Proper teaching about the Nationalism should be provided.
We are Bangladesh. We are the continua-tor of the ancient great Dravidian Nation. True defender of the own land, which is proven since the ancient time.
