> Nazi purges kill all minorities.

That’s not actually true. Traditional ethnic minorities in Northern Germany include the Danes and the Frisians. How did the Nazis treat them? Well, the Nazis viewed them as fellow “Aryans”. If the Nazis persecuted them at all, I can’t find any information on it.

The Nazis were not equally anti all minorities. In their minds, there was a ranking of the minorities, those at the top were to be treated with mildness, those at the bottom were to be completely extinguished by mass murder.

The idea that Nazis treated all minorities equally is arguably disrespectful (even if only unintentionally) of those whom the Nazis treated the worst.
