Hmm, well it's something that I've heard - I haven't really seen many Sylhetis. Is that racist towards black people as in from other countries, or even within BD? If it's within, I think it would be a similar situation within all of BD. Anyways, I think my dad is from Mymenshing (spelt right?) and my mum's side is from Kishorgonj (??)..but I'd say the base is Dhaka as a big city. I went to BD in 1993 when I was 5 years old...and the next time was in 2010 (last year!) for only 10 days. Other than that, I've never been to BD.
And lol at rice and curry. I'll tell you what, when I first started uni, I had to go off and live at a college (aka hostel/dorm, etc), and the food was different - steak and potatoes, spaghetti, sunday roast and so on - for about a month I was really happy. And then after that, I just got sick AS of mashed potatoes and other western food. Seriously, bhat and torkari is the best! And I eat with my hand too - none of this knife and fork business.
