Here's the essential common core of hatred and destruction in the doctrines of Communism, Nazism, and Environmentalism. Only the concretes differ, not the fundamental principle of hatred for human life and happiness.
Communism: The pursuit of individual self-interest causes monopolies, depressions, and exploitation of workers by capitalists. It must be replaced by self-sacrifice for the benefit of the working class and the Socialist State. Capitalists and landowners must be exterminated for the benefit of the proletariat.
Nazism: The pursuit of individual self-interest causes racial impurity, national decline, and exploitation of German workers by Jewish capitalists. It must be replaced by self-sacrifice for the good of the Aryan master race and the National Socialist State. Jews, Gypsies, and Slavs must be exterminated for the benefit of the German Nation.
Environmentalism: The pursuit of individual self-interest causes global warming, acid rain, and ozone depletion. It must be replaced by self-sacrifice for the good of other species—our "fellow biota"—and for the good of the planet, under the auspices of international treaties and a nascent Global Socialist State: the UN. Most of the human race must be exterminated for the benefit of exploited species and the planet. (This is what the environmentalist “extremists” already openly say. The “moderates” merely want to reduce carbon dioxide emissions by 90 percent and thereby reduce the American standard of living to that of a third world country, with a third world country’s infant mortality and life expectancy.)
