40 million Slavic killed? I don’t know where you get your information, but trusted sources say Jews where about half or greater than half. Slavic groups made up about 4-5million. I did find one privately owned website that said 40 million were executed, and it had no sources. I would attest that here is undocumented Slavic propaganda - hence why you need to say ‘Jewish Propaganda’
Anyways, you missed the point altogether - whether 6mil or 46mil, Americans have still killed 58 million through choice. Before we start saying how bad the Nazis are, we need to look in the mirror.
The Russians lost between 20-40 million of which about 6-8 million were POWS worked to death by the nazis in camps. Add to that all the Poles and Serbians killed and WW2 looks more like a war to exterminate the slavic race rather than the Jewish race. Hilter openly planed to murder the population of entire cities like Moscow.
