There is reason to believe, had Germany won the war against the Soviet Union, that attitudes over time could have changed. The initial solution to the Jewish Problem was expulsion from the Reich. Death camps were not built until two-and-a-half years after the English and French declared war on Germany, the United States had entered the war, and troops were fighting hard in Russia. Plausibly, a homeland for Jews would have been established in Madagascar or Palestine and there would have been no Final Solution. The Roma would have been forced to settle, perhaps in Romania, and quit their nomadic culture. Poles at first would have had no right of residence in the Reich and subject to the Generalgouvernement as a laboring class and, in time, might have been Aryanized, so to speak. This might surprise you but, being gay was illegal in the USA right up to 2003! In many Protestant U.S. states today, gays cannot marry! Back in pre-war Germany, homosexuality was an issue with regard to a perceived decadent culture of flamboyant effeminate or girly types such as was common in some Berlin night clubs of the Weimar Republic. It was believed that a good dose of work camp experience would teach them some manners. You might be shocked to learn that Communists were persecuted in the USA even after WWII, some executed and others in Hollywood blacklisted. Americans waged war in Viet Nam for years against Communists and have been blockading tiny Communist Cuba for decades. Try googling "Communism in USA". Ha! Right enough, Communism would have been proscribed in the Third Reich. Some religious cults were also banned, such as Jehovah Witnesses and active membership that targeted brainwashing of youth would have incurred a spell in a work camp. Today, Scientology is banned as such a dangerous cult in Germany. Traditional Catholicism and the Evangelic Church were well established and likely would have remained so in the Reich. After the defeat of the Soviet Union who knows what would have happened with Russian POWs? They might have been treated as German POWs were in the Soviet Union. Trying to see into a future that never existed can be interesting but must remain the subject of fanciful novels.
