What's this thing about Bengali nationalism as opposed to Bangladeshi nationalism?
Bengali nationalism is a crooked up non-existent ideology invented by India and BAL. It doesn't exist nor does this non-sense include our Islamic identity that shaped our culture as well. Its not even there in BD current constitution. And chakmas and other indigenous minorites won't agree to it ever. They won't ever call themselves bengalis.
Bangladeshi nationalism also include all those non-bengali citizens of our country and also gives us a distinct identity i.e shaped by ISLAM and different from WB which is nothing but India. Our nationality is bangladeshi. The term was coined by Pres.ZIA to unite the country after the disaster of 72-75.
