We should read the following, excerpted from "Espero Katolika" (January 1921), about the 7th Congress of Catholic Esperantists: "During that congress in Graz, we will have to found a very strong international army against the powers of blind revolution, against materialist Bolshevism, dangerous anarchism, the anti-ecclesiastic action of the Freemasons, etc..." So the Catholics are already using Esperanto to oppose our activity, to prevent our liberation.
