Now from all educated Muslim Bengalis learned and patronized Urdu, you shifted your goalpost to many Bengali families have traditional practice of Urdu. Expected.
I know your kind have this unnatural hatred towards Tagore for reason unknown, but neither Tagore has anything to do with it nor is your incoherent rambling and constant shifting of goalpost be termed as historical facts.
You are but just another clueless poster with presumptions and prejudice and if I were you I would back up my "historical claims" with proper citations. Friends of friends don't count as historical fact.
Only an idiot would assume getting an education means learning Urdu, or may it is the case in your community. It was not the case for Bengali Muslims during the reign of Nabwab or English or today! I have known many educated Bengali Muslims and their profession varied from medical surgeon to software developer to astrophysicist and I can assure you Hindustani was neither in their tradition nor in their curriculum.
Here is a quiz for you - Can you name one single Bengali laureate who composed anything significant in Urdu? Afterall Bengalis are overwhelmingly leaned toward art than any other part of subcontinent and would it not be strange that neither of this countless educated Muslims of yours who traditionally practiced and patronized Urdu, have contributed nothing to Urdu literature! After all I can recall many Bengali Muslims who have outstanding contribution towards Bengali literarture, one of the tower just beside the man you so hate, Tagore, and was his ardent admirer.
