Eh... No, first off, rude language for no good reason.
Secondly, No, the general population's IQ is not dropping. In fact, it is slowly rising, primarily due to the increasing availability of education in developing nations. This expanded access to education contributes to the enhancement of cognitive skills and knowledge, leading to a gradual increase in the average IQ globally.
Thirdly, the "Kalergi Plan" is absolute and utter bullshit. It's stupid bullshit conspiracy theory falsely claiming that Richard Kalergi designed a plan to mix white Europeans with other races via immigration. It stems from a misinterpretation of his writings, and is the silliest bullshit I've ever seen. It's a hoax, with no factual grounding, merely serving as a tool for spreading racist and antisemitic ideas.
You're better than this, be better.
If you won't, explode promptly.
