My Idea: Whites go into space, we create various fascist and traditionalist colonies at the lagrange points and terraforming Mars into planet for us alone. So far, basic "white separation via space travel and colonization and cutting off contact with earth" theory.
However while all this is happening, we collectively bombard Earth with White “aliens”, we flood the earth with white people for generations.
Through sheer numbers and time, we (peacefully) ethnically cleanse the niggers and indios into hexadecaroons or lesser, global minorities. (However, Sunni/Arabs and Jews will have to be exterminated upon our descendants return, there is no reconciliation there. These semites are not like the Berbers who were conquered, outbreed and absorbed by the Europeans to become modern day Southern Italians, Spanish, Portuguese and Greeks. Semites are incompatible with us, totally).
How do we do this? By using “transhumanist” technologies secretly and responsibly, we create the mass production of whites from genetic donations in combination with biocybernetic technologies such as cloning, Egg Creation from other cells, IVF, Sex Selection and Artificial Wombs. Then we send them down in waves to retake the earth.
This of course would have to be done in secret project kept away and kept in secret from our future societies’ general population, The Normies and the devote Christians, who are living wholesome anti-degenerate lifestyles and on average are producing 4.5 children per couple, naturally.
Hospitals, Universities, Spermbanks and Bloodbanks would typically provide the genetic material for the egg creation process under the guise of cancer treatment and medical research.
We can also create occasional “orphans from destroyed colonies from nigger and/or jew attacks”, Ectogenesis born children that can be adopted by the otherwise infertile or elderly natural-born couples, who could then integrate with regular society and the naturally born, bolstering our numbers further.
Within five generations we could retake the earth and continue exploring the stars.
