Why do you say that brother? People in Arunachal and Nagaland can speak better Hindi than say the South Indians, and we Assamese aren't far behind. Bengali is a State language in Assam, in Barak Valley. 6th Schedule and Autonomous Council areas like BTAD have their own Bodo language. We Assamese are welcoming to people of all ethnicities. Unlike South India, here you will find villagers atleast trying to converse with outsiders in broken Hindi. Every Indian citizen is our dear guest and will be welcomed to Assam. Our fight is only against illegal Bangladeshis, specifically miyas.
I can only laugh at the miya thread creator when he claims that our Joi Aai Axom is some kind of azaadi chant. These Bangladeshis never grow up.
The reference was to Hindi land people not Hindi language.
I heard somewhere on a TV show that people in Assam even consider people like Arnab Goswami as an outsider and there is a name/word for them.
