The recent spate of milkshake protests against the far right began in Warrington on 2 May. A young Asian man was being harassed by Stephen Yaxley-Lennon (a.k.a. ‘Tommy Robinson’, formerly of the BNP and EDL, now Ukip). As henchmen bristled around him, he defended himself with what came to hand. Yaxley-Lennon got another dousing in Wigan the next day, and Nigel Farage caught a banana and salted caramel coating in Newcastle earlier this week. Various professional hyperventilators have decried the apparent coarsening of British politics and predicted a rapid skate down a slippery slope. But this form of grassroots censure has a long history. George Eliot wrote of Mr Brooke being ‘disagreeably anointed’ under a ‘hail of eggs’ while campaigning in Middlemarch.
