It is an oppressive symbol. A symbol of girls and women, growing up in Britain, who are not allowed to have normal everyday conversation with men, who are denied education and often can not even speak English despite living in Britain for decades.
And more fundamentally face coverings such as balaclavas or crash helmets have ALWAYS been unacceptable in public-facing roles.
It does explain in the article, the process.
If you go here you can get stats: www.neighbourhood.statistics.gov.uk
Kirklees as a borough has 225,751 Christians out of a population of 422,458.
In Kirklees 024A (Savile Town area) the population is 2,226, of which there are just 5 Christians, 3 with no religion, 6 Sikhs, no Hindus or Buddhists, 1 other, and the rest are either Muslim (2,111) or not stated (100). Those are the kind of figures you would expect in Pakistan or Saudi Arabia, not England.
Diversity is great, but this does not represent diversity, it's an Islamic monoculture, and when you've got people going off to fight for terrorists we should ask why.
