I lived in London for about 8 years. I remember a taxi driver who was an immigrant telling me he’d lived all over the world including New York, Russia, etc, and he said London was the most multi-cultural place he’d ever lived. There were sort of even amounts of all different types of people and they all just got along in this big melting pot. I found people to be a lot more racist in the middle class cities full of “nice” white people (though I don’t think racism is that common in the UK). Most of my friends in London loved all the multi-culturism.
