Hitler's sales pitch to the German people was grounded in the idea that average German working people were victims and Hitler was their champion.

He claimed Jews, homosexuals, and socialists had "stabbed Germany in the back" by participating in negotiations for the Treaty of Versailles that imposed punitive conditions on the country, producing widespread poverty and an economic crisis.

If the German people were victims, Hitler told them, the villains were German minorities, promoting degeneracy like jazz and swing music, tolerance of homosexuality and transgender people, and the "international Jewish conspiracy."

Once the Nazis took power they banned books, outlawed drag shows and homosexuality, changed school curricula to remove mention of their atrocities in WWI, and rewrote election laws so they'd never again lose an election.
