them in the future, Hitler arranged for a formally commissioned exhibit in July 1937 of specially selected carvings, sculptures, and paintings. Once the exhibit was at an end, selected artists' works were banned from Nazi Germany. Well known was Hitler's vehement opposition to racial-mixing. He was also a natalist as he believed, as did other pan-Germans, that Germans had an obligation to procreate: Another area of concern for Hitler and which was mentioned by his childhood companion in Vienna, August Kubizek, was prostitution. Hitler associated it with venereal disease and cultural decline. Moreover, Hitler found the practice counter to proper family development and displayed a puritanical view in Mein Kampf, writing: He goes on asserting that prostitution was dangerous and intimated much more significant, destructive socio-political implications. Once Hitler came to power, his regime moved against all forms of sexual deviations and sexual crimes, especially homosexuality, which was prosecuted as a crime as many as 30,000 times between 1934 and 1939. Hitler's social conservatism was so extreme towards homosexuals that he deemed them "enemies of the State" and grouped them in the same category as Jews and communists; a special department of the Gestapo was formed to deal with the matter. Hitler's general perception about women was ultra-conservative and patriarchal, with their foremost task being a domestic one as a mother of children who worked contentedly at home, ensuring it remained clean and orderly. Meanwhile, it was the woman's role to educate her children to be conscious of their importance as Aryans and instill within them a commitment to their ethnic community. Consequently, Hitler believed women had no place in public or political life due to their differing nature from men. Like many Romantic artists, musicians, and writers, the Nazis valued strength, passion, frank declarations of feelings and deep devotion to family and community (with women being seen as the center of the family in Nazi Germany). So great was Hitler's influence in all political aspects of social life that even education for children was subordinate to his opinion. Profoundly anti-intellectual and against conventional education for children, Hitler determined instead that training and education should be designed to create young German "national comrades" who were utterly convinced of their "superiority to others". Moreover, Hitler wanted to create young German soldiers who were willing to fight for their convictions so they were accordingly indoctrinated by Nazi propaganda, trained in military discipline
