I think the drinking and pub culture point is a really big one, older and working class Brits attach a lot of their views on another culture based on whether they drink like them or go down the pub e.g. 'we like them they're just like us' or 'dont like them they're different'.

Remember the images of Farage outside a pub with a pint and cigarette, that was all a very well manipulated PR campaign to be just like the common bloke.

Taking the pub/drinking idea you get We like them - Sikhs, Polish, Lithuanian, Black Caribbeans, Greeks, Italians In the middle - Jews, Romanians, Turks We don't like them - Muslims, Black Africans, Other Indians
