When Luciana Berger, the Jewish mayoral hopeful for Liverpool, received the following message from John Nimmo on 8 July, “watch your back Jewish scum, regards your friend the Nazi”, followed by a warning that she’d “get it” like murdered MP Jo Cox, it was not quite water off a duck’s back. Nimmo – who also abused feminist campaigner Caroline Criado-Perez and MP Stella Creasey – may have been more of a compulsive bullyer than a die-hard neo-Nazi, but the incident made Berger “feel physically sick” as well as highly anxious and distressed. At the best of times, Jews generally don’t respond well to being told Hitler didn’t finish the job sufficiently. But Nimmo’s abuse must have felt like the last straw for Berger, who throughout her political career has dealt with a constant barrage of anti-semitic abuse. Her offices in Liverpool and London have round the clock security.
