In April 2018 Doyle created the fictional character of Titania McGrath, initially via a parody twitter account. According to Doyle, the character was designed to mock "woke culture".[13] The McGrath twitter account has been suspended for hate speech four times.[1][14] Doyle has written two books under the guise of the character. The first was Woke: A Guide to Social Justice published 7 March 2019[15] and a parody of children's books, My First Little Book of Intersectional Activism published September 2020.[16] In March 2019, Doyle was contacted by Rosamund Urwin, a journalist at The Sunday Times, who asked whether he was the person behind McGrath's Twitter account, due to the inclusion of several sources in McGrath's book that he had quoted previously. Though he denied it, he later revealed himself as the man behind the account.[13]
In February 2019, Doyle wrote a text in The Independent under the pseudonym Liam Evans.[17] The piece expressed dismay at comedy material performed on stage. After admitting he wrote it as a hoax, Doyle claimed the newspaper had published it without sufficiently checking the writer. The Independent's executive editor said that "The suggestion [...] that it is so outlandish that it must be false, is bizarre." Doyle also pointed out that if reading the fourth letter of every sentence in the text, it spells out "Titania McGrath wrote this you gullible hacks".[18]
Doyle is the co-author with Tom Walker of Jonathan Pie: Off the Record (2017).[20] He is also the author of Titania McGrath's Woke: A Guide to Social Justice (2019). It was positively received by a large number of celebrities including Ricky Gervais, as well as numerous right-leaning commentators. It was negatively reviewed by Alex Clark in The Guardian, writing that Doyle was making a cheap shot by poking fun at identity politics.[21] Doyle used the Titania McGrath pseudonym for My First Little Book of Intersectional Activism (2020), published by Little, Brown in September 2020.[16][22][23][24] He is the author of Free Speech and Why It Matters (2021)[25] and The New Puritans: How the Religion of Social Justice Captured the Western World (2022).[26]
