First all you can find a source to prove anything. I can very easily find on google sources and studies that claim the exact opposite of what you claim. I can find way more in fact. The consensus in every single scientific/academic field relevant to each of your claims is that you are wrong. Every one. The experts don't agree with you, clearly you haven't proven anything.

IQ does have a hereditary component passed down from your parents. With good schooling your IQ can be increased greatly, bad upbringings will decrease it. The west has had a more intellectual society with a schooling system for longer then Africa. A few generations of this has lead to higher averages. If we didn't school whites and did blacks it would be reversed. There is not enough evidence to say whites are just inherently smarter. Well educated people are smarter, regardless of race.

Look at Asians who were subsistence farmers 4 generations ago, not even literate enough to complete an IQ test. Yet now do better then white people in our own countries. There is no evidence in history of Europeans natural intelligence. For most of history it was a shitty bloody subsistence farming backwater. China was the intellectual and cultural capital of the world for thousands of years.

You're building a state with needlessly broad strokes. "Whites are smarter so lets have just whites." Why not "smart people are better so lets just have the clever." Oh because then that might affect you.

No one agree's with you, your 'science" is as flawed as your arguments, the world you want to create would suck, your perception of people's worth and character is skin deep and it's ironic that a movement of racial supremacists is filled with a bunch of gangling losers. Literally the movement for autistic young hateful white men who're mad girls don't want to sleep with them and that they don't have the intelligence or social skills to be successful.
