Well considering the fact that this whole thread (and this whole forum) is basically about being gigantic bigots against south asians
Bigotry are prejudice against the unknown.
Since i live in a city with 350 thousand indians and 250 thousand pakistanis (pretty much 45% of the population), in my case i can say that this kind of relationship WILL MOSTLY NOT WORK.
And you cannot say that this is due to the lack of knowledge. I live among pakistanis. And i know how hardline they are. A relationship between a polish woman and a pakistani man most probably will result in a lot of pain and misunderstandings, if not violence against the woman.
The same applies to some indians (being Indian Sikhs and Indian Christians the exception, since most of them are quite educated and relatively in line with European heritage).
