It’s been about seven months since I last wrote about how debates over Israel and antisemitism are dividing the American right, and in some ways the latest cycle of controversy looks like the last round. Once again we’re debating the programming choices of prominent podcasters. In March the instigating event was Joe Rogan giving a platform to Ian Carroll, a propagator of perfervid critiques of Israel; this time it’s Tucker Carlson giving a platform to Nick Fuentes, the Hitler-admiring leader of the so-called groyper right.

Because Carlson sits closer than Rogan to the centre of the Trumpist GOP, his Fuentes episode has set off a more dramatic intra-conservative war. But in each situation there are similar questions at work. How do you gatekeep a tendency – anti-Israel sentiment sliding down the slippery slope to Fuentes’ attacks on “world Jewry” – that’s clearly gaining influence within the populist ecosystem? Are the choices of prominent figures central to the drama? Is the right looking for a new William F. Buckley jnr, who once policed the paranoid and antisemitic boundaries of the conservative movement, to draw a clear anti-antisemitic line? Is it already too late to prevent a groyper future?
