Austria's Integration Minister Sebastian Kurz (ÖVP) wants to introduce tighter controls on Islamic kindergartens to prevent radicalization and said he believed the study was necessary because there is a danger of “parallel societies emerging”.
The author of the study, Ednan Aslan, is a professor at the Institute of Islamic Studies at Vienna University. He found that the religious education preached by several of the capital's 150 Muslim establishments led to "theologically-motivated isolation" and robbed children of their autonomy through "intimidation".
“In many of their publications the Muslim Brotherhood and Milli Gorus reject the Western way of life as an inferior worldview,” Aslan writes in the 178 page study.
He told the Standard newspaper that it was not acceptable that a representative of the Muslim Brotherhood, who runs a kindergarten in Vienna, should openly support the war in Syria or appear in a video in which he states that "we want to evangelize in Europe".
Many of the private Islamic preschools are subsidized by the City of Vienna - to the tune of €30 million - according to a report in the Krone newspaper.
Aslan said that the majority of the Islamic kindergartens were unwilling to participate in his study and that some took down their websites to make some data inaccessible. Only 71 out of 150 Islamic kindergartens agreed to be part of the study.
The Krone quotes one integration expert who contributed to Aslan's report as saying that it is as easy to open an Islamic kindergarten in Vienna as it is “to open a kebab shop”.
The study feeds into a wider debate about Muslim integration in Austria where the far-right Freedom Party (FPÖ) is leading the polls following the migrant crisis.

The FPÖ deputy mayor of Vienna, Johann Gudenus, has said that he wants to hold a special parliamentary session on the subject of Islamic kindergartens and a motion of no confidence against the head of the education board, Sonja Wehsely (SPÖ).
Gudenus added all kindergartens in the capital should be run by the City of Vienna, and not by private individuals or groups. The FPÖ also wants a financial audit of all monetary transfers to kindergarten operators and wants an investigation into whether any funds could have gone to finance terrorist groups.
The president of Vienna's Muslim community, Fuat Sanat, has said that allegations of "Salafist" education in preschools are "ridiculous".
