This is only true in the Anglosphere's literature.
Meanwhile, the Anglosphere spent a few centuries killing and dominating other races, and endulged in more ethnic-cleansing and genocide than Hitler could have accomplished in four-and-twenty reichs.
To be honest, both Hitler and Anglo-sphere are guilty are what we say, racial oppression. Since anyone not represent them, will get second or third rate treatment. This sin of discrimination may trace back the Ancient Roman time, which most of the time the so-called barbarians labeled as slave if they're captured during the war.
