Education institute, colleges, and universities have all been accused of being indoctrinating their students with false history.
The issue comes as the Holocaust Museum in Vienna, Austria, was vandalised and a swastika was spray painted on its premises.
Austrian Interior Minister Andreas Geisel said the vandalism had no place in the country, but that the centre is now a crime scene.
“We are looking at all the facts and will determine whether this incident is a crime or not, and we will investigate and if necessary prosecute those responsible,” he told reporters.
“This has nothing to do with religion and everything to do not only with the Holocaust but with other crimes of intolerance.”
The centre is part of the Austrian National Holocaust Memorial Museum, which is located on the city’s famous Brandenburg Gate.
It is the only museum in the world to be dedicated to the victims of the Nazi Holocaust.
The centre was built in 1935 and has a total of more than 300,000 pieces of art, including a sculpture of Hitler by sculptor Werner Biermann.
In 2015, Austria’s conservative government launched an investigation into the centre’s handling of the Holocaust, including claims of incitement.
In response, the Vienna-based museum’s board of trustees appointed a special committee, which was set up by the then Austrian Chancellor Heinz Fischer.
“The board of the National Holocaust Museum, the board of education and the staff of the centre are not involved in any form or form of indoctrination and the Holocaust has no place here,” the board said in a statement at the time.
It is unclear what prompted the attack on the centre, but it has been claimed by some critics that it was organised by a pro-Nazi group and the centre has not been accredited by the Vienna municipality.
The organisation has denied the claims.
The Austrian government has recently imposed a travel ban for many Austrian citizens due to the unrest in Charlottesville, Virginia, where a white supremacist rally descended into violence between white supremacists and counter-protesters.
The country has since been on edge following the violence.
