I assume most of you already know that Slavic Europeans are just as white as Western Europeans but almost every thread where the topic comes up some user will imply they're not even white.
Here is an exert from Ostara publications on Der Untermensch:
First issued in 1942 by the SS head office under the direct orders of Heinrich Himmler, The Underman has ever since been portrayed as “anti-Slavic,” “anti-Russian,” and “anti-Jewish.” In fact only the third allegation has any truth to it. The “anti-Slavic” and “anti-Russian” claims are merely the product of postwar propaganda, reliant on the fact that almost no one would have the chance to actually read the publication for themselves.
The reason for this was that after the war, the Allied occupying powers in Germany ordered all copies of the publication seized and burned.
Ideologically hostile Jewish propagandists have, for example, engaged in outright forgery and misrepresentation of its contents, while a single translation made by an ideologically sympathetic postwar publisher suffered from serious grammatical and translation distortion errors.
Far from being anti-Slavic, the reader will see that the SS Head Office publication portrayed Russians as victims of Communism—and then specifically blamed Jews as being behind Communism, and, ideologically speaking, inheritors of a far older, far eastern attack on Europe which had started with Genghis Khan and the Mongols.
Nowhere in the SS book are the Slavic people denigrated, and in fact many of the traditional Slavic nations are mentioned in text and photograph as being part of the greater European family. European nations specifically mentioned in this book include Portugal, Spain, Italy, France, Belgium, the Netherlands, Denmark, Norway, Finland, Italy, Switzerland, Slovakia, Croatia, Greece, Bulgaria, Hungary, and Romania.
