"please don't think that all the people who voted to leave did so for xenophobic racist reasons."
But the whole premise of leaving is universally build on xenophobic racist reasons or started with xenophobic arguments. The line between Euroscepticism and Anti-Europeanism is very thin, there is a market for "Breaking point" ads.
The fact that 9/10 of most anti-European parties (even on the mainland or those a Nigel Farage is dweeping with) is xenophobic/racist from nature is extremely telling.
