Milo Yiannopoulos is done for. The Breitbart editor, who made a name for himself by peddling ‘unsayable’ things, and riding the waves of right-wing adulation and left-wing horror which followed, finally stumbled over a genuine taboo. A recently recirculated tape of remarks on the benefits of relationships between adolescent boys and older men has finally caused the American conservative establishment to cut its ties with him. He has lost his slot at CPAC, the premier right-wing political gathering in the US, which has previously hosted defenders of internment and slavery; Simon & Schuster, the publisher which gave him a $250,000 advance for a book (working title Dangerous) and defended the offer on the grounds of freedom of speech, has cancelled his contract. Last night, amid rumours of staff threatening to walk, Yiannopoulos resigned from Breitbart. One might marvel at what stirs the underused muscles of conscience in a Breitbart staffer were the temptation to schadenfreude not so overwhelming.
