A Danish academic is challenging several accusations levelled against Florence Bergeaud-Blackler regarding her book, *Le Frérisme et ses réseaux* (The Muslim Brotherhood and its Networks ). These criticisms were subsequently picked up in France , notably by *Le Monde *. According to the French anthropologist, this new counter-investigation confirms that some of the attacks on her work were largely disproportionate.
Published in 2023 by Odile Jacob, "The Brotherhood and its Networks" is devoted to the Muslim Brotherhood and its networks of influence in Europe . Florence Bergeaud-Blackler argues that the Brotherhood movement should not only be studied from the perspective of classic religious or political activism, but also as a strategy of gradual implantation in Western societies.
The book has sparked numerous debates in France and abroad. In Denmark , where it was translated under the title Broderismen , the controversy took a particularly heated turn when two researchers, Lene Kühle, a professor at Aarhus University, and Manni Crone, a researcher at the Danish Institute for International Studies, questioned the scientific rigor of the work.
A new reading of the case
On September 11, Danish academic Tina Magaard, former lecturer at Aarhus University, published a lengthy analysis of this case in the weekly newspaper Weekendavisen .
Her work consists in particular of reviewing several disputed passages from Florence Bergeaud-Blackler's book, then returning to the original sources in order to verify the solidity of the accusations made against her.
And her conclusions are particularly favorable to the French anthropologist.
According to Tina Magaard, some critics have blown minor errors or editorial issues out of proportion and blown them out of proportion. She also believes that some of Florence Bergeaud-Blackler's positions have been misrepresented and that several of the criticisms leveled against her would not stand up to careful scrutiny of the texts and references used.
One of the examples highlighted concerns the work of Swiss journalist Sylvain Besson. Tina Magaard claims that a quote used in the critical dossier was presented without a key word, thus altering the meaning of the original sentence.
Mistakes acknowledged, but the accusation deemed disproportionate
Florence Bergeaud-Blackler never claimed that the Danish translation of her work was completely error-free.
In her detailed response to the criticisms, she notably acknowledges several incomplete references, typos, some factual errors, as well as translation or presentation problems.
But she has contested from the outset the escalation of these imperfections to accusations directly affecting her scientific integrity.
According to her, a pagination error, an imperfect reference or an editorial blunder cannot automatically be equated with falsification, plagiarism or fraudulent scientific practice.
She also points out that a very large proportion of the criticisms leveled against her book concerned formal elements. In her analysis, she states in particular that 186 out of 249 critical comments focused solely on missing page numbers.
For Florence Bergeaud-Blackler, the problem lies precisely there: the accumulation of minor flaws gradually created the impression of an overwhelming case, whereas the real nature of the criticisms was much more heterogeneous.
A 96-page response
The anthropologist also points out that she had responded very early and in detail.
As early as 2024, she claims to have produced a 96-page response examining point by point the accusations made against her in Denmark.
Her central argument has remained constant: her book can be discussed, challenged, corrected on certain points or subjected to scientific criticism, but this does not justify, according to her, transforming an academic controversy into a general questioning of her professional integrity.
This distinction is central to his defense.
For Florence Bergeaud-Blackler, criticizing a hypothesis or challenging the interpretation of a source is part of the normal functioning of research. Accusing a researcher of plagiarism, falsification, or manipulation, however, is much more serious, because it is no longer just their reasoning that is attacked, but their professional credibility.
When controversy arrives in France
The Danish controversy then found an extension in France.
On February 14, 2026, Le Monde published a profile of Florence Bergeaud-Blackler by Youness Bousenna. The article notably reiterated the criticisms made by Lene Kühle and Manni Crone regarding the book's scientific rigor.
Various referencing problems are then raised, along with quotes deemed distorted, claims presented as insufficiently documented, and suspicions of plagiarism.
Florence Bergeaud-Blackler strongly disputes this presentation.
She notably criticizes the newspaper for giving significant visibility to the accusations coming from Denmark without giving equal space to the detailed response she had already produced.
In his view, editorial problems and much more serious accusations were thus placed in the same category, giving the reader the impression of a uniform succession of scientific failings.
A new question for Le Monde
Tina Magaard's publication now changes the context.
If several accusations used against Florence Bergeaud-Blackler are indeed based on questionable interpretations or erroneous presentations of sources, as the Danish academic claims, the question of their being repeated in the French press necessarily arises.
How were these accusations verified before being reported? And should the new evidence published in Denmark lead to a re-examination of how the French researcher was presented?
Florence Bergeaud-Blackler believes that these questions are now unavoidable.
For her, Tina Magaard's counter-investigation is not just an additional defense of her book: it calls into question the solidity of certain elements that had contributed to publicly establishing suspicion around her work.
A controversy that goes beyond his personal case
The anthropologist also believes that the case raises a broader question about the freedom of research.
His reasoning is as follows: if a researcher working on Islamism, the Muslim Brotherhood or other particularly sensitive subjects risks having a scientific disagreement turn into an accusation about his professional integrity, this can have a chilling effect on the entire academic world.
According to Florence Bergeaud-Blackler, the danger is therefore not only that of individual injustice.
There is also a risk of self-censorship: young researchers may hesitate to work on certain topics for fear of the professional, reputational or personal consequences of a controversy.
That is why she believes that her case goes far beyond her own personal journey.
A shift in the balance of power
For nearly two years, Florence Bergeaud-Blackler found herself in the position of having to respond to criticisms of her book and her method.
Tina Magaard's publication is changing this balance of power today.
The Danish researcher chose to return to the original documents, quotations, and sources. Her analysis concludes that several important accusations levelled against Florence Bergeaud-Blackler are, in her view, insufficiently substantiated or based on distortions.
This does not mean that "The Muslim Brotherhood and its Networks" is exempt from scholarly debate. Like any research work, it can be discussed and challenged.
But the nature of the debate is changing.
The question is no longer simply whether Florence Bergeaud-Blackler should respond to her critics. It is also whether those who have relayed the most serious accusations against her should now re-examine their own interpretation of the case.
After being repeatedly pressured to justify herself, Florence Bergeaud-Blackler now has a new and substantial element in her defense. And this time, the accusations themselves are under scrutiny.
