For real. Lenin’s introduction to The State and Revolution is evergreen:

What is now happening to Marx’s teaching has, in the course of history, happened repeatedly to the teachings of revolutionary thinkers and leaders of oppressed classes struggling for emancipation. During the lifetime of great revolutionaries, the oppressing classes constantly hounded them, received their teachings with the most savage malice, the most furious hatred and the most unscrupulous campaigns of lies and slander. After their death, attempts are made to convert them into harmless icons, to canonize them, so to say, and to surround their names with a certain halo for the “consolation” of the oppressed classes and with the object of duping the latter, while at the same time emasculating the essence of the revolutionary teaching, blunting its revolutionary edge and vulgarizing it. At the present time, the bourgeoisie and the opportunists within the working-class movement concur in this “doctoring” of Marxism. They omit, obliterate and distort the revolutionary side of this teaching, its revolutionary soul. They push to the foreground and extol what is or seems acceptable to the bourgeoisie. All the social-chauvinists are now “Marxists” (don’t laugh!). And more and more frequently, German bourgeois scholars, but yesterday specialists in the annihilation of Marxism, are speaking of the “national-German” Marx, who, they aver, educated the workers’ unions which are so splendidly organized for the purpose of conducting a predatory war!
