i have no problem with your post, you are not wrong! but I have read everyone's history (bd, pak, foreign journalists) unlike you which is only your version! Awamileagu was a large party- it had both pro pakistan leaders and separatist leaders. Mujib had to control both. The first person who raised Bangladeshi flag as a student leader of Dhaka university was my uncle and Mujib wasn't happy with him. Mujib never called for independence! It was Zia actually!
First friend BD history is not taught here. I have read from neutral source.
He was active member of Muslim League during pre independence. he supported pakistan in 65 war with India. It all started with Ayub failure and his strong One center plan. Mujib want separate identity and suggested 6 point.
And YES he call for independence on 7th March 71 at race course ground, Dhaka.
Any way its my version that you version. Be happy with whatever you have and whatever we have.
