Yes multiculturalism has worked in the UK since Roman times and more lately since the huge influx of Europeans during the 19th century. If you look at the demographic you will see that for example in 1800 there were 6,000 Jews in the UK, just before the 2nd world war there were 400,000. People of a particular culture always initially live and work together for at least the first and often the second generation, that's normal, look at all the British immigrants ( sorry they call themselves expats don't they) in Spain and Portugal- they generally make zero effort to learn Spanish or Portuguese and club together so they can communicate easily and the same is often true of 1st generation immigrants here. There's no need to get hysterical about it at all, it's just normal human nature and it's gone on for centuries, here and abroad, and yes I like it, I have friends of all religions, races, creeds and colours, and we manage every week not to harm or insult each other, because being a violent moron is nothing to do with colour or ethnicity and everything to do with being a decent human being, so yes multi-culturalism works and will continue to do so. What does worry me is the right wing elements on our streets who appear to want it not to.
