You just can't go and settle there,it'll look awkward to them as they are living there for thousands of years.At first they need to be included with the mainstream and thats our responsibility as majority.On top of that the kind of Bengali people settled there are not that friendly to them.The ground reality is they are not given equal opportunities.
Zia settled them (poor bangali) in an unplanned way.That started the problem.Before that pak govt made the kaptai power plant which washed away their residences.
These unpatriotic guys ruined the country.
