There are non-Muslims living in Bangladesh and they are a significant portion of our citizenry.
However we are all Bangladeshis at the end of the day.
Bangladesh govt. encourages and preserves cultural heritages/languages of the non-Muslims such as Chakma, Garo, Mro, Khasi and Tenchangya peoples. These populations are taught using their own languages and alphabets. There also job and educational quotas for non-Muslims and non-Bengali speaking folks.
But the overwhelming trends are clear. Folks sitting in Delhi some thousand miles away cannot decide what is better for those in Seven sisters region. No one is suggesting the breakup of the Indian union at this time, but being part of the Union must be moderated by economic uplift. It cannot be simply one way.
Pumping oil in Assam and
lifting of 'faida' by the Indian central administration has to BENEFIT Assam in real tangible ways and not just the center only. There is a reason why groups like ULFA. KLNLF and NDFB got popular support. The root reason was perceived uprooting of indigenous populations by economic means by Hindi speakers. See it for what it is and move on to benefit your indigenous peoples.
Stop listening to dhokeybaaji propaganda by Central Govt. Sanghis - Bangladeshis or Muslims are not your problems or enemies, they are not in your region to uproot your tribal and indigenous populations. It is the Hindi speaker Sanghi @$$holes who are trying to populate your region with Hindi speakers.
The GDP per capita for Bangladesh is now double or more that of WB and Assam, probably more than that of Nagaland and Manipur as well.
Are the people and their leaders in Dispur, Shillong, Imphal and Kohima happy with this economic state of affairs? Are they happy with their land being simple backward picturesque touristy backwaters and live off the measly few tourist Dollars/Rupees dispersed by kanjoos cow belt tourists every year? So be it.
It'd seem however that the people of the seven sisters would like to improve their economic lot by trade with Bangladesh and have their eyes on a better future. Forestry. agricultural and mining raw materials and products are just the tip of the iceberg. The train is leaving at the station, get on board now.
