What did the Nazi platform say about who belonged in Germany and who should be excluded?

The correct answer is propaganda

Every two years we come across (unpleasant, for some) political programs, whether on radio, television or the internet. Candidates holding little children in their laps, kissing old people, hugging beggars, promising improvements in health, education, transportation, leisure and culture. What few know is that this practice became common in the 1930s, at the present age, in Germany, thanks to Joseph Goebbels, propaganda minister in the Nazi government of Adolf Hitler.

Born on October 29, 1897 in Rhineland, Prussia, Goebbels fought in the First World War (from which he was released for having one leg bigger than the other), which intensified his nationalist spirit. Skillful speaker, in 1924 he was admitted to the German National Socialist Party. A fervent party follower, Goebbels became Hitler's right-hand man. When the third Reich was established, he was appointed Minister of Propaganda.

Goebbels was responsible for creating the “füher” myth. Filmmaker, journalist, literary and philosopher, had a unique rhetoric. It produced exciting films publicizing Nazism. It showed a better, prosperous and happy Germany with the supremacy of the Aryan race. His films stimulated ethnic prejudice, xenophobia, patriotism and heroism and condemned Jews, claiming that they were guilty of accumulating wealth, exploiting the people. According to the writer Roberto Catelli Junior: “Advertising and films not only criticized enemies, but also created models of behavior to be followed by Germans, such as being economically restrained and avoiding luxury1.” To consolidate his ideas, Goebbels censored the entire German press, closing newspapers, publishers and radio and television stations. Goebbels' propaganda had an effect. Thousands of Germans joined the party and contributed to Hitler's Holocaust by torturing and killing their own countrymen.
