Wiki is your friend! All I can make out that it's very complicated. I know London has a huge Indian and Pakistani community and the stereotypes overlap. I know that the whole Indians-are-often-doctors-and-driven stereotype is here too, for Hindoestanen (though their history is different their origin is also in India) were easily the first immigrant community to become succesfull here. We don't have the Indians-and-Pakistanis-are-conveniencestore-holders, though. But hey, being portrayed weird nerds is slightly better than being portrayed as the allies of the Joker, y/y? :P

LOL, fair enough.
