I think if it’s true that he’s a racist - and it is - it’s worth saying it. In addition there are two instrumental reasons we should say it.

First, Farage’s whole schtick has been to say: ‘You can oppose immigration without being a racist’ and the related argument ‘You shouldn’t be called a racist just because you want less immigration’. Proving that he is, himself, a racist makes both arguments deeply suspect.

It also more broadly crystallises what’s evil about him for those of us who already hate him (most people!) and shows exactly why he needs to be kept out of power at all costs. If I’m in a swing seat at the next election (currently safe Labour but will there be anywhere safe by 2029?) this is the kind of thing that will make me go ‘I don’t have to like it - and I don’t - but I’m voting for Lib Dems/Greens/whoever is best placed to beat this guy’.
