Strasserism became a distinct strand of Nazism that whilst holding on to previous Nazi ideals such as antisemitism and palingenetic ultranationalism, added a strong critique of capitalism on economic antisemitic grounds and framed this in the demand for a more worker-based approach to economics. However, it is disputed whether Strasserism was a distinct form of Nazism. According to historian Ian Kershaw, "the leaders of the SA included Gregor Strasser did not have another vision of the future of Germany or another politic to propose". The Strasserites advocated the radicalization of the Nazi regime and the toppling of the German elites, calling Hitler's rise to power a half-revolution which needed to be completed.
