On this topic how's this for irony. I'm lucky enough to be able to get from NZ to France (& the UK) for a few weeks most years, and one of the two Brit couples I stay with in rural France (who are by no means racist) told me that one of the main reasons so many of their fellow Brits have upped sticks to live similarly is 'to get away from the blacks.'
I Might be missing the irony there. Just sounds like unironic racism.
The irony lies in the fact that these Brits my friends know, who left the UK to 'get away from the blacks', might now following the Brexit vote be forced by EU regulation to return to the UK to live amongst them. Or else told to take up French (EU) citizenship.
