The anti-Deutsch movement broadly started as an attempt to oppose a resurgence of murderous German nationalism triggered by Germany’s reunification in 1990 according to Berlin-based sociologist Peter Ullrich. Speaking to Novara Media, he explained that the anti-Deutsch movement feared reunification would lead to a “fourth Reich.” They blamed something inherent in the German nation – whether culture or DNA – for having led to the Holocaust, and thought history would repeat itself if Germany was reunified and independent. One formerly anti-Deutsch thinker Jürgen Elsässer in 1990 demanded “the destruction of the German state and its […] replacement by a multi-ethnic state as well as the dissolution of the German people into a multicultural society.”
It's an interesting read.
Semi-unrelated but how reliable is the source? I don't think I've seen it before
