What is a bigot? That term is now so overused — to describe everyone from foreigner-hating skinheads to feminist academics who question transgenderism — that we have lost sight of its meaning. It’s now basically a stand-in for ‘unpleasant’, deployed against people we simply don’t like or understand. But bigot has a very specific meaning. It doesn’t mean gruff or un-PC or even ‘worried about immigration’. It means, as the Oxford English Dictionary spells out, ‘intolerance towards those who hold different opinions to oneself’. A bigot is someone who is so ‘obstinately and blindly devoted to his own church, party, belief, or opinion’ that he comes to loathe those of a different church, party, belief or opinion. Which raises a pressing and intriguing question: in Britain’s EU referendum debate, who, really, are the bigots?
