In June 2020, Linehan criticised comments made about J. K. Rowling after she made comments that were called transphobic. He linked to a blog post featuring screenshots of abuse Rowling had received, describing those who wrote them as "ignoring the abuse received by women who speak out against gender ideology" and "literally useless". Hozier, named in Linehan's tweets, responded by saying Linehan was conducting an "obsessive little culture war". On 27 June, Linehan's Twitter account was permanently suspended following what Twitter called "repeated violations of our rules against hateful conduct and platform manipulation". In December 2020, Linehan evaded the suspension with an account posing as a trans man, which he used to call Colm O'Gorman "a traitor to women, gay people and yourself" for signing an open letter published by the Transgender Equality Network of Ireland; the account was banned but Linehan claimed to have created another.
