I get the fact that you personally need to promote hate toward B'deshis as traitors. But long term - logically speaking, '
نفرت' toward a nation of 160 million plus is pointless and does not benefit Pakistan.
I honestly believe most Bangladeshis are not even interested about asking forgiveness from Pakistan or crying about being victims in spite of loud proclamation from some trolls here at PDF. Why should they? Bangladesh as a nation is certainly not doing any worse economically or on any measure of success, such as health, education or poverty.
However the lessons as a group/nation they learnt fighting a civil war will not be forgotten from that event - which also concerns India to some extent.
I think people simply make too much of Hasina's anti-Pakistan proclamation/propaganda which is basically politics to ensure her survival as a PM.
I wonder how many Pakistanis share your 'traitor' view (or even care). When I visit my Pakistani friends and chat over a chilled glass of 'Pakola' (most of them are upper middle class folks from educated technocrat 'khandaans') all they talk about is how common our Bangladeshi heritage (religious as well as social) is with Pakistanis. I believe Bangladeshis share far more social commonalities with Pakistanis than with Indians. It is quite pronounced in expat communities in the UK and in the US.
There are quite a few married families in our social circle where either of the husband or wife happens to be Pakistani. No one bats an eyelash about it and no one cares. We go to the mosque together, the children from the families study at the same Islamic schools and celebrate/observe Eid, Ramadan, Shab-E-Barat and Shab-e-Meraj together. We even celebrate and get together during some of the musical performances.
At the end of the day we should celebrate our similarities - and not promote pointless division and hate.
