What is it about J.K. Rowling that brings out the worst in the far-left?

If hell is other people, Twitter is the Devil’s noticeboard. Occasionally, though, its asteroid-inviting awfulness unearths a little insight into human nature, specifically when our instincts clash with our ideology. Take J.K. Rowling, author of the Cormoran Strike series who has also dabbled a little in children’s fiction. The Scottish novelist is a well-kent supporter of left-of-centre causes and has backed up her conscience with her coin. Her broadsides against Donald Trump and Brexit have made her an enemy of the intemperate right. Far more perplexing is that strain of leftist that bears ill-will towards someone whose politics are barely distinguishable from Neil Kinnock’s and who — I do so hate to be vulgar — has expended a good chunk of her treasure funding their movement.

Rowling’s tweets criticising Jeremy Corbyn’s support for Brexit and the Labour Party’s toleration of anti-Semitism attract extraordinary opprobrium from the far-left. Jeremy Corbyn does support Brexit and, when it comes to Jews, the Labour Party is a racist endeavour.
