I've got no sense of British identity, really, nor do I particularly like it here, but I'm white, and middle class, I guess, and born in Sheffield. I never know, really, if people are immigrants or born citizens or whatever: nor do I particularly mind. I care much about them as a person than as an identity.
Not that, you know, I'm apathetic about things. I care about most things: but immigration, eh. I find it hard to engage with that one.
