One can safely assume it ain't gonna happen, and so the discussion is pure fantasy.
Not there's anything wrong with fantasy. As long as one remembers that is what it is.
I was going to mention that in my reply. Unfortunately, it is all too true.
But because discussion is what we're here for...
1. America has gone so far that if the "American Nazi Party" were to win a relevant election the UN would publicly involve itself starting there.
The American Nazi Party is completely irrelevant now. It got attention when George Lincoln Rockwell was alive, but only because he used shock tactics to get it. But if they did get any votes, yes, they would be ousted immediately and a more tolerant candidate would take their place. A party with less extreme, but still very nationalistic, views, would have to gain ground slowly and make their opinions the norm among Americans. All of the barriers of political correctness would slowly have to be eroded until we could talk about segregation seriously again. Seeing as how this is happening in Europe (to some extent) right now, it may not be too much of a fantasy to imagine it happening here.
2. How exactly do you move millions of Africans back to their homeland? Give each some $ and a plane ticket? What do you do with those that refuse to go?
They all cry about wanting reparations for slavery anyway. Tell them they'll get it, if they leave the country. We could always straight-up deport the African nationals who aren't citizens back to their countries. As for the ones that don't want to go: there would be plenty of people, especially a lot of whites, who would not want to live in a white ethno-state. Too many people are attached to their love of multiculturalism for them to give it up in favor of realistic solutions. They would just get a separate part of the country for themselves to race-mix and get all of the "cultural enrichment" that they want, away from the whites who want to separate, And then we'd leave them be.
3. What do they do once they're in Africa? The continent is already dysfunctional, what happens when you dump millions more on it?
We forget about them after that. It's not our problem what brown people do in their own countries, unless the want to invade us, And then we'd deal with them properly.
I have yet to come up any reasons why retiring alone to a farm is not the best individual solution.
It really is. But if one cares about one's ancestors, and heritage, and this planet, one has to give any kind of fight they can. We can all jump ship and let the whole thing fail if the fight becomes completely hopeless and futile.
