"It was a protest vote"
Ok so there is evidence out there that some people voted as a protest vote or to kick the "elite" it was discussed by all media outlets on the night. Its been repeated by others since.
"they were lied to"
Can you disagree that some of the leave campaign was lies? £350m?
"they're racist"
Can you deny this either that some of the vote was anti immigration because of prejudices?
"they're thick, old, they're rich, poor, uneducated, over privileged, bigoted, it's just whatever suits your argument at that moment."
The rest goes for the all of that.
