They Are Bangladeshi Not Bengali- Most people don’t know the difference between Bengali (WB, India) and Bangladeshi identity. They are two different identities. Bangladeshi people are often confused as Bengali. They are quite different. They (Bangladeshi) have separate language with accent, history, culture and geographical demarcation. A Bangladeshi may claim to be but not exactly a Bengali. They use Bengali as co-identity.
