This alleged plan for the systematic extermination of the "German race" through allegedly deliberate immigration, the subsequent closure of mixed marriages and the subsequent emergence of hybrids, is what the right-wing call the "Kalergi Plan" and sometimes they have more names for it, but that is what they mean by it.

If this sounds like old Nazi propaganda now, it is because it is old Nazi propaganda, because it is exactly the propaganda that the National Socialist German Workers Party used to "justify" the extermination of the Jews. That is also the reason why it is called the "Kalergi Plan", this name comes from the old Nazi propaganda, because it said that Richard von Coudenhove-Kalergi (the founder of the pioneer of the European Union) had just developed the Kalergi Plan and that Jews like him would now deliberately and systematically spread out in Germany to deliberately marry Germans and thereby, as already said, deliberately mix the German race so that Germans would disappear as a race. With the Germans who believed this inhuman nonsense of the NSDAP, then of course fear and finally hatred (for the Jews) developed and exactly this was what the NSDAP wanted to achieve by spreading this agitation.

But already in the original Nazi propaganda there are surprisingly some gaps in the thinking, logical mistakes, and other things that don't really make sense, which makes you realize that it was just something that the Nazis told the Germans to scare them and to incite them against Jews.

The most obvious problem is that there is no proof for the existence of this "Kalergi Plan" and normally you would have to call the European Union the "Kalergi Plan" because ONE (although not THE) European Union was the only thing he really planned. Now you could say; yes, of course, there is no proof of the Kalergi Plan, because it is secret. But then how do you know about the plan? Now one could say that one knows from Kalergi's books. But also his books don't contain such a plan and if you really read his books you'll realize very fast that he was a completely peaceful pacifist and that he had absolutely nothing against any people, especially not against his own, because contrary to the Nazis' claim he wasn't even a Jew but a Christian and from the descent even German (well, Austrian). But he had a positive attitude towards Jews (and also towards all religions and cultures in general) and stood up against their discrimination and against anti-Semitism, and he also stood up for peace and international understanding in general and wrote countless books against anti-Semitism, against dictatorship, against dictators, for ethics, for idealism, for peace, and for international understanding.

Therefore he was of course a very big thorn in the side of the Nazis and they started to slander him very early. In his manuscript for his unpublished sequel to "Mein Kampf", a certain Adolf Hitler personally dedicated whole chapters already in 1928 to slandering Kalergi whom he calls a "half-breed" and "commonplace bastard" and his idea for a European Union he calls a "worthless" "pacifist-democratic-pan-European muddle state", an "unnatural structure" and a "dangerous utopia" that would not last and would only flood the world with disease bacilli, and emphasizes again and again that you cannot unite peoples peacefully but only through struggle, and suggests that in order to provide stability you have to eliminate "inferior" races. 37)

There is a sentence in one of Kalergi's many books that the Nazis used as "proof" for the "diabolic Kalergi plan to destroy the German race" and took it out of context, but in this sentence, he only assumed that in the distant future the human races would probably mix more and more. It is only his assumption about the distant future - it is not a plan and not even demand and it does not specifically refer to the German people or even call for their annihilation, nor did he propagate (spread) racial mixing, but he did look at it critically.
