Such awful luck that they left their home countries and migrated to a white country thousands of miles away in a misguided hope for handouts and easy living, yea. Really bad "luck."
Britain is one of the most multi-ethnic countries on the planet. This is not a 'white country'. Why do you insist on viewing the world and differing political opinions based on the colour of people's skin? It amounts to nothing but verbal diarrhea when you combine a false vision of a country thousands of miles away from you and then proceed to call this a victory for nationalism. The vote has nothing to do with English/British nationalism; it's about democracy and disaffection with taxation without representation. People in Britain of every ethnicity and background have voted to leave the EU. You are basically proving yourself to be no better than the people you claim to despise with such mental gymnastics.
