The stain and shame of antisemitism has coursed through her majesty’s opposition since Jeremy Corbyn became leader in 2015. - Jeremy Corbyn

Jewish organisations know full well that vilifying Corbyn as an antisemite would drastically reduce his appeal, as antisemitism resonates only among assorted antediluvians, troglodytes, and fruitcakes. In other words, the irrefutable proof that Corbyn’s pursuers don't believe a word they're saying is that by labelling him an antisemite they hope and expect to isolate him. However, as the accusation is manifestly a red herring, it's also possible that the current hysteria will pass most people by entirely, not because they are unconcerned by antisemitism but because it hardly occurs to them as an issue at all. If the controversy has an effect it will be restricted to exacerbating divisions in the Labour leadership and perhaps also adding to a more general perception that the stories promoted by mainstream media are fake news.
