Agreed, we all 'breed' in the UK, but it's the birth 'rate' that matters, as any mathematician knows. Muslims have a much higher birth rate than the rest of the UK, who are following an ever-decreasing path with a birthrate less than the 2.1 statistically needed to stop the population becoming extinct. So, the maths are there, they just need interpreting correctly.
Which brings me to another point, which is; why is there not more support for single parent families instead of downcasting them? They are the ones helping to keep our population afloat.
