I am not sure if ethnogenesis will help too much. There are many biracial and multiracial people who identify as black, and want to stick it to whitey. Jesse Williams for example. Also any move to blend African Americans will bring a huge backlash from the Left. Most 1/4 or 1/8 blacks look white (Stephen Graham, Wentworth Miller, etc), and so Leftists will say this is a form of eugenics. Black academics like Thomas Sowell are seen as pariahs, while he provides some of the best options for growth. Handouts weaken people, communities and nations if they become a crutch rather than a temporary (very temporary) measure.
There needs to be a complete rejection and destruction of the new Left. The old Left did some great things, like ensuring gays have full rights, and expanding some needed social programs. The new Left has become very anti White and very anti West, and it stokes a lot of tension. It glorifies weakness and victim hood. It creates phenomenal divisions. Diversity to some degree is strength, diversity in extreme leads to division. The liberal media continuously attacks Whites, and tries to enrage minorities to attack Whites. It blames everything on White people. 'Social science academia' started this whole movement a long time ago. It denies common sense. If you read everything from Pew studies to newspaper articles, they have an anti White slant. When you have big headlines saying, 'White minority soon!', it's a lie because if you include White Hispanics America will be more than 75% white even in 2060. But this is one way you can turn minorities on each other. Not to mention the fact that the Left basically bows to Islamism.
When you have intelligent young people going to college demanding safe spaces, arguing over debunked 3rd wave feminist theories and the fact that Whites are an evil race, you have a problem. When you have a culture which hates the family unit and legalizes massive infanticide, you have a problem. But worst of all when you have a movement which demonizes values of hard work, sacrifice, honor and loyalty, you have a massive problem. A civilization will not survive with the loss of such values.
America needs to move towards the Right. A new Right. The old Right is a joke, with religious buffoons and ignorant racists. People like Trump should not be running for President. Wall Street is also a huge threat to the American people as it basically places the values of the elites before the common man.
The new Right would be a blend of nationalism and ethnogenesis, and a return to American exceptionalism. Ethnogenesis and nationalism build on each other, as the latter is an extension of tribalism. And tribalism is partly genetic.
America needs to return to aggressively continue pursuing engineering and science as it has historically. More NASA less BLM. We could have been on Mars building bases were it not for the fact that the Left has severely weakened America. We have the technical know how, but the political will is not there.
America needs to go back to its roots, of pioneering and exploration. Of work ethic and the will to win. Of being the best of the best, no matter. A mixed populace with these values, could conquer the universe.
China is pursuing genetic engineering full steam and securing African investments. Islam is the largest religion (and socio-political movement) in the world for all intents and purposes and will grow. Russia is still a major player. The Left ignores that there are cultures which want to destroy the West, and will be willing do so to win. The winners in the global race for dominance are not going to be the most politically correct, but the hungriest and most willing to sacrifice for the cause. The politically correct will be the first to be eaten alive. They are one of the biggest enemies of America and the West in general.
Oh and I'm brown so to all those who will say I'm some white supremacist, can kiss my ***. Win or die, that's the rule of nature.
