He's an ignorant knuckle dragging scrotum faced buffoon, his party is flailing to the point where most of his support comes from the even further right factions of EDL thugs, and people who think Nigel Farage is too posh to protect the working classes of Britain.
People constantly call for him to be banned from every social network, his party struck off the electoral commission, and booted thoroughly up the booty by Danny Tickle. But I think letting him have his say can only make him even less popular, same goes for the likes of the EDL. We don't even have to give them much rope for them to (figuratively) hang themselves with their constant hatred fuelled drivel.
