Feorag NicBhride's "The pernicious influence of immigrants in the UK" is a non-exhaustive catalog of the many awful travesties wrought by we dirty foreign immigrants on the pure, clean shores of Britain, including tea, the Conservative party, football, and the English language.
As Charlie Stross says, "if you're one of that 40% [of British residents polled who do not think the UK has benefited in any way from immigration].you can stop reading my books right now, because obviously they are of no benefit to you."
* The English language (the Anglo-Saxons, much modified by the Normans)
* TheEnglish legal system (the Normans). The Scottish one is based on Roman law.
* The music of Handel (emigrated from Germany to England), Freddie Mercury (from Zanzibar), Cliff Richard (Indian), George Michael (Greek), Status Quo (Francis Rossi is a mix of Italian and Irish), Vanessa Mae (Chinese) KT Tunstall (Chinese) and practically everything in the charts right now, it seems.
* Football – the contributions of British Italians and people from the Caribbean are far too many to list. In fact, it would be best to ignore sport altogether. I mean, once the England cricket team was captained by someone called Hussain, the whole enterprise was doomed.
* James Bond – Ian Fleming was of Swiss origins.
* The Conservative and Unionist Party – Iain Duncan Smith (grandmother was Japanese), Michael Portillo (Spanish descent), Nigel Lawson, Baroness Warsi, Michael Howard (Romanian parents) and Winston Churchill (whose mother was an American immigrant).
* Wicca – this might seem to be the only genuinely British religion, but Dorothy Clutterbuck, who taught Gerald Gardner, was born in India. Gardner himself spent most of his formative years in Asia.
* The railways – built with Irish labour. Even though the labourers were British citizens at the time, they didn't want to be, and this should be respected.
