He is an author about Classism and an analyst on anti-democratic tendencies in Germany, including those of the AfD.

Kemper conducted critical analyzes of classism and neoliberalism (klasseismus.de), racial biology and organized anti-feminism (diskursatlas.de).

He sees these developments as the basis for the emergence of the "Alternative for Germany" and published the book “Right Euro-Rebellion” in July 2013 in which he identifies the AfD as a reservoir for these currents.

Kemper not only warned against the emergence of a right-wing party, but was also the first to accurately determine the start-up financing from the Finck Group.

[3] Under his pseudonym "Doris Neujahr", the right-wing radical author Torsten Hinz criticized Kemper in 2009 for his open participation in the German-language Wikipedia in an article in the nationalist "Junge Freiheit".
