I don't have any experience with Muslim Bengali dinner parties or anything, but I can add one thing. I do not want to generalize, but I can see clear differences between Hindu's in my University (mainly from Sri Lanka and india) and Muslims from India/Pakistan etc. From my experience, the Hindu's integrate a lot better. They befriend people from all religious background, even gay people. They dress western, and even though they don't celebrate Christmas religiously, they chill with people and have a type of christmas party, having some beer and overall having a great time. Muslims on the other hand are different. They don't wish people merry christmas or a diwali, they don't usually befriend non muslims, their parties are boring (with exception of food) all they do is read Qur'an, talk about religion and pray afterwards, not much of a party. They also do not integrate. Again, this is my experience from University. Overall, I say that Hindu's integrate better, and the same goes with Sikhs. Also, atleast Hindu's do not have any Dawah tables handing out CD's and booklets. They keep their beliefs to themself, same with Sikhs.
Pretty much spot on. You're canadian so your and my campus experience is pretty much same.
Of course I would say you have to separate the Muslims "by name" ones from the rest. They are no different at integrating than any other kuffar.
Is Sylhet like the most bass ackward part of B'desh?

Atleast that's what I've heard from Bengalis from other areas like Dhaka...
Yes and no. The ones that came to the UK are basically labour class - some who were working the tea plantation a generation ago.
