The most conservative estimate of the Muslim population in the UK is about 4%. Now, unless your reading white supremacist websites, I don't see why you reiterating and implying that there are too many Muslims.
You need to realise, it doesn't have anything to do with whether your an asset or not. If xenophobia takes over. Your credentials are pretty much irrelevant. Ask the Jews of Nazi Germany and the Japanese in internment camps in the US during the war or perhaps the Boer farmers who were in concentration camps in South Africa by the British. Did their educational achievements or entrepreneurial spirits save them in anyway?
Pakistanis and sub continent Asians, despite what people say about them, have pretty much contributed to the development of Britian more than their counterparts. Only the Irish could challenge them in that regard. Post World War II, it was these 'Pakis' as you describe them, that built Britian back into an economic powerhouse.
Never forget that. Stop reading xenophobia based nonsense and maybe you will be a fair human being.
