anticommunism

noun

1. (uncountable, usually)Opposition to communism.

   “In the main, anticommunism in postwar America meant opposition to the kind of dictatorial state socialism that existed in Russia and that many Americans saw as a negation of everything America stood for. In the 1946 campaign, for example, when I talked about the "communist-dominated PAC," my remarks were generally understood in this context of dictatorial socialism versus free enterprise.”
