 Instead, eco-socialists feel that increasing repressive counter-terrorism increases alienation and causes further terrorism and believe that state counter-terrorist methods are, in Kovel and Löwy's words, "evolving into a new and malignant variation of fascism".They echo Rosa Luxemburg's "stark choice" between "socialism or barbarism", which was believed to be a prediction of the coming of fascism and further forms of destructive capitalism at the beginning of the 20th century (Luxemburg was in fact murdered by proto-fascist Freikorps in the revolutionary atmosphere of Germany in 1919).Kovel criticises many within the Green movement for not being overtly anti-capitalist, for working within the existing capitalist, statist system, for voluntarism, or for reliance on technological fixes.
