Bat Ye'or

Her books thus possess a scholarly veneer, which has led many on the forums of the internet where those who obsess about the perceived threat of Islam gather to quote her words as though they were of unimpeachable authority. … And this is despite the stream of howlers and ludicrous overstatements that litter her prose. Bat Ye'or is the pseudonym of Gisèle Littman (née Orebi), an Egyptian-born British citizen and Swiss resident. She is a major figure and "ideological leader" of the Islamophobic counter-jihad movement and author of several virulently anti-Muslim books.

She is most notorious for coining the conspiracy theory called "Eurabia," which notably served as the main ideological inspiration for the Islamophobic mass murderer Anders Behring Breivik. The conspiracist sense of the word Eurabia was first adopted by Ye'or in 2002, but the term had been used in a non-conspiracist sense by others as early as 1975 in the journal Eurabia, which was published by the European Coordinating Committee of Friendship Societies with the Arab World. The conspiracist sense of the term Eurabia was popularized by journalist in her 2004 book The Force of Reason, wrote about Ye'or.

Ye'or's sympathizers (Ayaan Hirsi Ali, Bruce Bawer, Niall Ferguson, Ishad Manji, Melanie Phillips, and ) have referred to her as a historian,  but among professional historians, her writings are not well-regarded. Ye'or's academic standing is complicated by her having published books with a legitimate academic publisher, Fairleigh Dickinson University Press,    and by counter-jihadists to sometimes claim that she has academic credentials,  though she has none.
