1. Bangladeshis are Muslim first and Bengali second.
However we don't up with B.S. so when a drunk general who has group sex and orgies sends in troops to kill us (i.e. Yahya Khan) we fight back.
2. In Dhaka the majority of fans will support Pakistan over India in cricket.
I can send you the videos and links if you do not believe me as that what happened.
a: We can marry Pakistanis, and some of us do.
b: We eat halal, they eat halal.
c: We fast for 30 days, they fast 30 days
d: We pray in the mosque, at least jumah, if not 5 x day, and so do they
e: We observe Eid and do Qurbani, and so do they.
f: We say Asalamu'alaikum when we meet each other, so do they.
g: We say masha'Allah, insha'Allah, astaghfirullah, so do they
3. The difference between us and them is that they are south-Asian/south-west Asian and are more militant e.g. they have stronger tribe/caste system and identity, obsession with being tough, feuds etc
We are calmer, do not have a tribal system or feuds and are known for being quiet, maybe even self-effacing or timid.
We find them a bit arrogant and mouthy (I keep my distance from Pakistanis) and a bit coarse and rude. If we meet a Hindu we would never insult him or offend him and be hospitable to him.
Here in the UK, most Bangladeshis are Sylhetis and we are exactly like everything above I have said.
Some Pakistanis and the way they would treat Hindus especially those from the lower-classes is extreme and they would view you not as subhuman but basically an animal. They even kill Shias and other Sunnis let alone Hindus.
We Bangladeshis are nothing like that as your dad saw. Nothing to do with Islam but cultural interpretations/misinterpretations of Islam.
4. Water terrorism refers to India's control and misuses of dams to deprive neighbours of much needed water, and also this misuse of water as a strategic weapon.
