I am replying to the pain topic of the thread

Bangladesh is an Independent Country and all the Bangladeshi people are know as Bangladeshi

The official language of Bangladesh is Bengali, the world mother language day 21st february is from Bangladeshi official language Bengali. At 1952 Bangladeshi people fought with Pakistan for the right to have Bengali as their official language and 21st February 1952 they got their deserved right.

In India there is a state named West bengal and citizens of the state speak Bengali language.

All the people around the world speaking bengali language is known as Bangali.

And I believe there should be no confusion anymore.

As a Chinese speaker I think there are a lot Chinese dialects available around the world. In China when I travel from one province to another I even sometimes dont understand the dialects.
