The Parole der Woche's weekly wall newspaper declared that the United States and Britain had agreed to let Stalin take Europe. Using propaganda to present the Jews as being behind both helped juggle the issues of opposing "plutocracy" and Communism at once. After the invasion of the Soviet Union, propaganda resumed, quickly linking the attack with British forces, which simplified the task of attacking both Communism and "plutocracy" at once. The Nazi movement was overtly anti-rationalist, favoring appeals to emotion and cultural myths. It preferred such "non-intellectual" virtues as loyalty, patriotism, duty, purity, and blood, and allegedly produced a pervasive contempt for intellectuals. Both overt statements and propaganda in books favored sincere feeling over thought, because such feelings, stemming from nature, would be simple and direct. In "Mein Kampf", Hitler complained of biased over-education, brainwashing, and a lack of instinct and will and in many other passages made his anti-intellectual bent clear. Intellectuals were frequently the butts of Hitler's jokes. Hitler Youth and the League of German Girls were overtly instructed to aim for character-building rather than education. The theory offered for Nazism was developed only after practice, which had denigrated expert thinking, only to seek out intellectuals who could be brought to support it. Sturmabteilung speakers were used, though their reliance sometimes offended well-educated audiences, but their blunt and folksy manner often had their own appeal. One popular Munich speaker, declaring biological research boring, called instead on racial emotions; their "healthy ethnic instincts" would reveal the quality of the Aryan type. A 1937 essay aimed at propagandists "Heart or Reason? What We don't Want from Our Speakers", explicitly complained that speakers should aim for the heart, not the understanding, and many of them failed to try this. This included an unrelentingly optimistic view. Pure reason was attacked as a colorless thing, cut off from blood. Education Minister Rust ordered teachers training colleges to relocate from "too intellectual" university centers to the countryside, where they could be more readily indoctrinated and would also benefit from contact with the pure German peasantry. An SS paper declared that IQ varied inversely with male infertility, and medical papers declared that the spread of educational pursuits had brought down the birth rate. This frequently related to the blood and soil doctrines and an organic view of the German people. "Blood and soil" plays, for instance, depicted a woman rejecting her bookish fiancé in order to marry an estate owner.
