It's dreadful language, but it's nothing new. We've seen their disgusting posters - "Old white people please die" and "No country for old white men". People like Owen Jones have legitimised the use of the word 'gammon', a racial slur for white people, while it's acceptable for pro-Leave MPs to be harassed in the street when Remain MPs are off limits. On Question Time last night a young lady in the audience accused Farage of 'preying on racism'. This from the side that deploys racial slurs in the open.
This is just a very brief selection. Call it out.
