"When sexuality is prevented from attaining natural gratification, owing to the process of sexual repression, what happens is that it seeks various kinds of substitute gratifications. Thus, for instance, natural aggression is distorted into brutal sadism, which constitutes an essential part of the mass-psychological basis of those imperialistic wars that are instigated by a few. To give another instance: From the point of view of mass psychology, the effect of militarism is based essentially on a libidinous mechanism. The sexual effect of a uniform, the erotically provocative effect of rhythmically executed goose-stepping, the exhibitionistic nature of militaristic procedures, have been more practically comprehended by a salesgirl or an average secretary than by our most erudite politicians. On the other hand it is political reaction that consciously exploits these sexual interests. It not only designs flashy uniforms for the men, it puts the recruiting into the hands of attractive women. In conclusion, let us but recall the recruiting posters of war-thirsty powers, which ran something as follows: ‘Travel to foreign countries — join the Royal Navy I’ and the foreign countries were portrayed by exotic women. And why are these posters effective? Because our youth has become sexually starved owing to sexual suppression."
