They will do to Britain what the Mexicans are going to do to the USA. They will simply, in time, take over Texas, New Mexico, Arizona, Mexciaforniastand, probably Nevada, Idaho, Oregon, Washington, Oklahoma, etc. They will start in the west and move up the leftist coast and eastward. Hell, already cities in Georgia have been taken over by illegals, such as Cedartown, GA, which is heavily Mexican now. In Britain, the Islamics will out number the Brits in time. They will vote them out and change it to their empire. Same here. Hispanics have multiple children, while white American families are not having more than one or two. Blacks are not having as many. Spanish will over take blacks and then whites as the majority. Then they own the ballot box. A lot of people phoo-bau this, but it has already started. Just look around. I was born and raised in Alabama. Went away for many years in the military and came back home after 30+ years away. When I was a kid and high school person, I never, ever, saw Mexicans here. Now they are all over the place. Everywhere.
I don’t care if Mexicans “take over” as long as they are American “mexicans” who were born or naturalized here. Mexicans are Christians. Yes, there are some serious cultural problems, but most of those are the result of class differences between the people who jump the border (who are mostly from the lower class) and the average American. These problems could be done away with by deporting the illegals. Middle-class and ambitious working-class Mexicans who emigrate here legally are by and large good citizens, and they are welcome in my county, town, and neighborhood.
As for Muslims: I don’t trust them. I wish them no ill, and I feel for the good ones that just want to live in peace, but I don’t trust them. Their culture is incompatible with ours. Ideally, we’d deport them all, but that would require a constitutional amendment (or a state of martial law).
