No, just expanding it; note my use of the word 'excluded' in my third paragraph above. It's partly about poverty and partly about a wider sense of exclusion.
In a multi-ethnic society, two extremes have to be avoided. One is imposed uniformity eg: we're all Frenchmen and all the same, we all look and speak the same, and are all secular humanists. The trouble is with that model is that anyone who does not conform is automatically excluded, whether you be a devout Jew, an evangelical (and I know quite a few who have been 'excluded' eg: from their jobs or their families for being open about their faith), or a practising Muslim (if you're a practising or devout Catholic, you can just about get away with it as it was the majority religion, but even that's pushing it nowadays); or indeed a British ex-pat who insists on not learning French and just hanging out with other ex-pat Brits. That's the French model (also the Swiss to an extent) and it doesn't work.
The other extreme is the idea that everyone is free to express their identity as superior to the exclusion, denigration or plain ignorance of everyone else's. That is multi-culturalism gone mad and results equally in ghettoisation. That is the danger that the British model has always to be wary of (hence Trevor Phillips' warning to which I have earlier alluded), and indeed we see this most clearly in Northern Ireland with its tradition of sectarian violence.
Between the two lies the happy medium - unity in diversity with tolerance and mutual respect for each others' identities.
