The problem is that the Muslim foreigners in the U.K. have used their religion and the cry of 'racism' and 'religious bigotry' as a lever to obtain 'rights' and concessions from the government allowing the Muslim population (many on 'the dole') to get away with outrageous acts under the cover of 'religion' and, 'scared' Sharia Law, which condones acts that are moral and legal crimes in any civilized nation. The Muslims in England have established themselves in neighborhoods that were once filled with British citizens. Yes, that is typical of immigrants but with Islamists, they use the religion to supersede civil & criminal laws and by doing so, undermine the British society. From what I've read, the British Muslims have made many demands and the government has usually acquiesced to the latest demand.
So, that 8% seems to be pretty powerful, much as the (probably) 2% of Americans that identify as homosexual have changed what was once considered an illegal perversion into a constitutionally-protected behavior that is now taught as 'normal' in our public schools. Homosexuality is ceaselessly celebrated by the leftmedia and Hollywood. Those who engage in homosexual behavior have more legal protections against assault than non-homosexual citizens. And it only took about 35 years for this insanity to grow to where it is, today, in America. This is how you lose your country. In the U.K., the Muslims, with their 8% population, have effectively won the battle, thanks to idiotic multicultural dreamers in charge of the Labor government. I take the British experience as a warning. I hope other Americans do, too.

You're making the implicit assumption that the non-white population is predominantly Muslim. In fact the Muslim percentage is only about 4%. It's worth remembering (something that's usually overlooked here) that among the non-white population the Muslim influence is balanced by large numbers from other groups, such as Hindu and Sikh, with long experience of resisting attempts at Muslim hegemony in their country of origin.
