Sadly, mainstream public opinion in this country is given shape by tabloid newspapers and their flavour of the month.
A lot of this stuff is hyped up to sell papers.
What we do have in the UK is a lack of a clear self image which opens up people to worrying that they are losing it with immigrants when they were never quite sure about what it was in the first place.
Firstly, with regards integration. If you're worried about the "muslims" not integrating, what are your neighbours names and how often do you speak to them? What local activities do you take part in? The UK is drifting away from close knit communities and it's -nothing- to do with immigrants.
Dole claimants, there's a million more scumbag uk born and bred claiming various benefits illegally (and think they have a RIGHT to do this) than there are immigrants. Yes there are a number of bad apples that have emigrated here but there's many more already here.
