I must start a collection of replies like this. My tweets are mostly about what a nobody I am, yet the hordes of people who nevertheless feel it's important to prove how wrong I am think that telling the world how clever and credentialed they are will be a devastating tactic.

He's still frothing away in my Notifications that I need to prove that Jeremy Corbyn is an antisemite, which I didn't say in the tweet in question, and I don't think I've said anywhere else either. But I wonder why so many people have had to devote so much energy to denying it.
