I really only shined in to point out the anti-Slavic white bent of the old nazis, which we're not in disagreement about.
Here's some Cambridge stuff delineating the separate nature of Anglo Saxon, Norse, and Celtics as peoples.

Here's where the nazis tried to pretend that Anglo Saxons and Scandinavians had a common root, in Atlantis:
"...Only in the 1920s did a strong partiality for "Nordic" begin to reveal itself, and for a while the term was used almost interchangeably with Aryan.[19] Later, however, Nordic would not be co-terminous with Aryan, Indo-European or Germanic.[20] For example, the later Nazi minister for Food, Richard Walther Darré, who had developed a concept of the German peasantry as Nordic race, used the term 'Aryan' to refer to the tribes of the Iranian plains...
...and Alfred Rosenberg wrote of a "Nordic-Atlantean" master race whose civilisation was lost through inward corruption and betrayal.[54] According to Rosenberg, the Nordic race had evolved in a now-lost landmass off the coast of Europe, perhaps mythical Atlantis, migrated through northern Europe and expanded further south to Iran and India where it founded the Aryan cultures of Zoroastrianism and Hinduism. Like Grant and others, he argued that the entrepreneurial energy of the Nordics had "degenerated" when they mixed with "inferior" peoples."

Notice how the Norse 'degenerated' by mixing with 'inferior' peoples. The nazis felt that the Scandinavians had intermixed with Laplanders and Slavs.
In short, you can find all kinds of conflicting statements from the nazis about other peoples, depending on whether they're trying to shine them on, absorb them, or justify attacking them.
