So why is an eight-year-old allegation being recycled now? I think we need to look no further than March’s national conference of the so-called Unite Against Fascism, which the Huffington Post summed up with its headline "UKIP must not be allowed to influence politics and immigration."
I add the emphasis to identify UAF’s real target: not UKIP, but democracy. In a democratic society, we vote for who we think can best run the country, city, region or village, and - crucially - we recognise that other people have the right to vote for candidates we disapprove of.
This comes on the heels of the controversy over Paolo di Canio’s appointment as manager of Sunderland. Having played for Celtic, Sheffield Wednesday, West Ham and Charlton Athletic and managed Swindon with no fuss, former miners are being agitated because he may hold views that middle-class socialists who so detest blue-collar culture disagree with.
Karim’s Facebook message to UKIP sounds like a UAF declaration of intent: "Bring it on Farage - we're ready for you in the north west". Must we be prepared to defend ourselves and others at the ballot-box if we look like we might practice what Karim and the UAF stormtroopers consider the wrong sort of democracy?
