But some believe any old shit that vile hate rags like the Daily Mail bombard them with - let's not pretend that xenophobia and ignorance don't exist among voters in the UK.
You apparently believe this data somehow proves your point... which in a roundabout way, kind of proves mine.
The data you've linked to doesn't give any figures for immigrants - presumably most of the people of Black, Asian and Mixed ethnicities are actually British.
Are you saying that those who voted to leave because of immigration issues were ignorant of what they were voting for?
