Bhai please don't insult people without knowing all factors. You are re-writing history essentially.
You being Hindu (or Muslim) I don't care, but abusing people as a group is against the rules in this forum.
You don't represent all Bangladeshis (or even some of them) and hurling abuses at Urdu speakers is not welcome just because of "perceived" historical wrongs.
History will be judged by all, not one person.
@waz,
@WebMaster bhais please note.
Too many false flaggers in this forum and non-Bangladeshis with Bangladeshi flags at that.
OP confessed he does not speak Bangla, in one other post. This is the problem with the Bangladesh section, Indians hijacking our narrative as usual and "speaking for Bangladeshis".
In Bangladesh (or even Calcutta, before partition), most reputed Bengali families (that of Suhrawardi for example) spoke Urdu at home and with most of their business/professional colleagues. Urdu and Farsi were court languages prior to the British rule.
