The main problem is that there are unscientific approaches to maniplations of IQ data in order to push a racist agenda,

Life is racist because evolution was racist. That's the final pill for anyone who still refuses to accept the harshest scientific facts.

There's a book called the 10,000 year explosion that answered the question what are the chances that every single Human being on Earth could be the exact the same? It was like 1 in 1 quadrillion or some other unfathomable number that no one here can imagine.

Basically, it's up to Liberals to explain how is it possible for Nature to be equal? Dogs aren't equal to cats, birds aren't equal to ants. Lions are not equal to fish. Some animals have wings, others have sharp claws, some can see in the dark and other animals are completely blind.

We don't call this racism, we call these biological differences. And the brain being one of the most important organs in existence is not exempt from these factors. If Africans had the exact same selection pressures as Europeans and Asians did then none of this IQ controversy would exist. But for most of history, the darkest parts of Africa had people living in mudhuts, without written languages or an understanding of the wheel. This hollywood sci-fi idea that Africa was always home to Space Shuttles and skyscrapers is a myth. Notice when Europeans arrived on the continent and begun the process of colonization, did any African city even begin to resemble a Western one?

And once Europeans were ejected from the continent, Africa went back to being a primitive mess like it always was before?

That's the price of denying race and IQ. History is the great equalizer and the most advanced civilizations to exist have always been either European or East Asian in origin. No one else has come close to eclipsing them.
