In 2019 Flynn was told that his new book "In Defence of Free Speech: The University as Censor" would not be published by an English publisher, Emerald press, who had previously accepted it and scheduled it for publication. It was thought "too controversial" under the United Kingdom's laws about 'hate speech' as the intent is irrelevant if it is thought likely that "racial hatred could be stirred up as a result of the work." Academica Press later published the book under the title "A Book Too Risky to Publish: Free Speech and Universities".
