Read their literal fucking documents on race policy. Read Hitler. Read Himler. Read Hans F. K. Gunther. How are all the Nazi supporters completely ignorant about Nazi policy literally all the time? Why do I have to explain to you the shit you should already believe by being a National Socialist. And don't give me an excuse about 'meh meh I'm a white nationalist'. You're not, your tolerance to child rape in England, and the support of the Palestinian movement proves you don't give a shit about Whites.

National Socialist Ideology sees Slavs as inferior sub-species because they were the polluted-blood descendants of Aryans, hence their degenerate behaviors, their untrustworthiness, and their lack of forming nations outside of judeo-bolshevism organizing. Germans were of the "Northern Race", which were the closest, least-polluted-blood descendants of the Aryan hyperborean race; which is why they were superior. Africans are not even descendants of the Aryan hyperboreans, meaning that they are entirely outside of the whole Aryan-blood descendency lineage, nor do they even have ancestry with any of the earlier pre-cursor races prior to the Aryans. Hence, the source of African blood is evolved from the soil, and possibly from animals. Therefore, they are barely even "human" in the way that we would understand it. Giving them weapons isn't really any different from the German Army using horses or guard dogs.

Slavs, by definition, are a kind of corrupted-blood race. One of the big conflicts within internal Nazi race politics was the use of Slavs in SS units specifically because of their corrupted blood. Hitler, and many others, were against using them at all in the SS because they wanted the SS units to be as Aryan as possible. Himler argued that, by virtue of seeing some Slav units were capable of good combat, it meant that there was Aryan-ness, or even Aryan-blood that may have been injected into the Slavic sub-species from events like the Tutonic crusades. Hence, the most Aryan-blooded Slavs could and should be recruited because some of the Aryan blood within this sub-species could be saved.

I'm not asking you to read some communist historical account. I'm asking you to read the primary source material.
