On Archive.org, you can read Count Richard Coudenhove-Kalergi’s book, The Totalitarian State Against Man. It’s not a long book, only 199 pages. Reading it may provide clues (or not) to the motivations of the ideologues who are in control of our world.
As best I can understand Coudenhove-Kalergi’s ideas, he believed that mixed races were superior to more homogeneous races. He doesn’t really get to this aspect of his philosophy until well into the book.
As to the title of the book, I find it misleading; it might make you actually think he was not a friend of totalitarianism, but let the reader judge for himself.
Anyway, it’s available to read for those who are interested in this man who obviously was one of the main architects of this crazy world we find ourselves in in the 21st century.
