Repeated addition of unsubstantiated claim from one user edit

One user has presented a personal opinion as fact three times. This user insists on attributing the authorship of Araki Yasusada's writing to Kent Johnson. Specifically, the user keeps adding "The real writer of the poems is Kent Johnson, professor of Highland Community College in Freeport, Illinois, though he denies it."

While Kent Johnson is commonly believed to have been the author of the Yasusada texts, (1) there are other individuals commonly suspected to be the authors as well, such as South American poet and musician Javier Alvarez or Japanese poet Tosa Motokiyu (whose name is itself is a pseudonym connected to an unknown individual or set of individuals); (2) Johnson is only *known* to have been involved in the dissemination of the Yasusada texts; and (3) no record exists of Johnson claiming to have been the creator of the Yasusada texts. The intensity of this user's beliefs do not transform the belief into knowledge.
