Please note that the Rohingya are forced to live in camps in Bagladesh and the Bangladeshi government doesn't want them either and no one was allowed into those camps to give them aid until recently when a children's charity had been given permission. So, ID'ing themselves as Bangladeshi in order to be recognised and have more rights in Myanmar is counterproductive since it's probable that Bangladesh wont recognise them either or give them any rights if they attempt to go there with Myanmar documents, in all !likelihood their true Rohingya ID will come out, after all they speak a different language! - Halil
