...and realize that all of their white man's guilt for centuries of the British Empire having been a colonial power is not going to be assuaged by making others, who were once oppressed by the British, British citizens. No it is not surprising that 38% of south Asians who were polled said they do not feel like they are British - see: http://news.bbc.co.uk/2/hi/uk_news/6921534.stm.
So, many of those Pakistani Muslims are not going to melt in the pot, nor are many of the other folks from places like India, Hong Kong, or anywhere else. Just because you gave them British Citizenship does not mean that they will not seek to destroy your way of life, if by nothing else, then by not assimilating and spreading their own culture within your borders. In fact, as can be witnessed from what is going on across the pond, it seems as if many of those folks would rather destroy the British way of life and replace it with something a bit more fatalistic.
All the best,
