1) Suppose Punjab bifurcation in 1966 had not happened.

Haryana, parts of Himachal remained part of "Punjab" state.

Haryanvis & Himachalis were told to give up their language/speak only Punjabi since the state was named Punjab. Or else get out/ go to UP.

Would that be fair ?

2) Suppose Bihar became part of Bengal/merged with Bengal as Congress wanted in 1950s (Bengalis rejected then) & the state was name only "Bengal".

And then Biharis were told to give up their Language/speak only Bangla or else get out/Go to MP or UP

Would that have been fair ?

3) So how does that logic apply to a (historically) multilingual state like Assam ?

Where Goalpara in the West ,Barak in South & rest of Assam were always linguistically different entities

U take a multilingual entity, name it "Assam" & Bengalis must give up their Language ?

4) As if Bengali is alien to that part of Assam...

One can check any book on linguistic history of NE. Till 19th century Bengali was the most preferred Lingua franca of the state. Used by distinct groups/ kingdoms to communicate with one another in absence of common Language.

5) Imagine if Telugus in TN, Karnataka, Tamils in Karnataka, Tulu, Konkani, Marathi speakers in Karnataka are told to GIVE UP their mother tongue. Knowing/writing the official State language with fluency Not enough, 1 has to give up their mother tongue.

Wouldn't that be absurd ?

6) Xtian missionaries since 19th century have been fuelling ethnic divide, Tribalism, esp Bengali Hindu sentiments in NE

The reason is whatever "Hinduism" u see among NE tribes is bcoz of Bengali cultural influence (Kamrup was only an extension of Bengal before Ahoms came)

7) Rajas adopting names, titles similar to the ones used by Bengali Zamindar/Bhuiyas, using Bangla as common medium to communicate with other kingdoms, Bengali script to write their own Languages, overall Sanskritization --spread of Hinduism =spread of Bengali cultural influence.
