In England for my honeymoon in 2011, I found the country to be a friendly multi-racial country, which is quite different from the England I was born and grew up in back in the late 1960's-70's. At that time, racism was par for the course. As a half-Indian/half-American-mongrel hybrid, hardly a week would go by without my hearing "Go back to your own country," finding a brick thrown through a window, or other vandalism of our house.
After my 2011 experiences, I was quite surprised by the Brexit vote. Still, 48% of voters voted against Brexit, and a vote for Brexit does not necessarily suggest racism, but could instead be cast due to the economic concerns associated with mass immigration.
My mother, on the other hand, was glad about the outcome of the Brexit vote; "I hate to think of them as being different from what I remember, even if it means they're still racist sons of b's."
