I'd compare Rheinland, as depicted, to 1933-1938 Germany, rather than the Weimar Republic. Not quite at the stage of war, but past the stage of a peaceful, democratic government.
Some Neo-Nazi invader actually did try to start such an SS faction pre 500 mil days. He got booted quickly for slinging insults and swears towards Caylith, and probably for offensive names and symbols.
There's no policy of discrimination in Rheinland, as far as the material I've read goes. It's at least strongly implied Rheinland is gender equal (half of the Kriegsmarine is run by a woman, there was a female Kanzler, there has been at least one senior woman officer), and by far and by large Rheinland is relatively isolationist anyway, far from a "master race" or "extermination" notion.
Lighten up. Israel can enjoy "The Producers", a movie featuring a tap dancing effeminate Hitler singing "Springtime for Hitler" in a play penned by an ex Nazi to help finance the tax scheme of two Jewish media moguls.
