Britishness

I was just thinking about what it means to be British and why the BNP are not what I consider the best of British.
To me, it's political. Britain is built on secular(ish) liberal capitalism. I'd personally like it to be more secular, more liberal and less capitalist.
I'm often told by those that come here that they are so proud and happy to be here, often more so than those born here who are often desperate to leave.
To me, British-ness is all in the mind, and not at all in the pigment or the genes
