Bengali nationalism adopted by Mujib after 71 however it was replaced by Bangladeshi nationalism similar to Pakistani nationalism. You need to study our transformation after the revolution of 75.
I as a Bangladeshi proud to announce that I am fluent in Urdu. You are new in this forum and obviously not aware that I have defend Urdu over Bangla and still convey my message that Urdu was right and appropriate language for united Pakistan. Yes, it true that many Bangladeshi dislike Urdu but not all. Urdu still being teach in Bangladesh but smaller scale.
There are probably more Masjid in Dhaka city then Lahore and Karachi combined. There are more Masjid per kilometer in Bangladesh then any Islamic nations. We are surrounded by Hindus from three side and Buddhist from one side yet we are still Muslims and going strong. If our
Iman was weak and we did not believe in
tauheed then we would have been eliminated by Bharati influence long ago.
We have separated from West Pakistan because it didn't work out but that doesn't mean Bangladeshi left Islam. There was a brief trail after 71 but revived it with full sewing after 75.
Bangladeshi would do it for me.
