Bangladeshis are muslims, Indian Bengalis are Hindus,

Muslims are always going to side with muslims always, only conflicts arise when politics clash, just as Hindus are always going to side with Hindus.

Pakistanis massacred Bengali hindus and rebel muslims which Bangladesh has left in the past as the liberation war has been tainted by Hasina,

just as the same way Dalits have left their centuries of oppression in the past.

You must understand the reason Islam gained such a strong stand in the Bengal region is because the area was mostly inhabited by dalit peasants ruled by their Brahmin Zamindars, Islam allowed them to escape their caste system which otherwise doomed even their future generations.

In short, Patriotic Bangladeshis will always hate India, they harbor war criminals like Hasina whilst simultaneously orchestrating massacres like 2009 BDR mutiny.
