African Americans have been here as long as us

Only true if you count a small portion of servants. There was not a large free or slave black contingent in the colonial era. There were zero during the initial seed colonies like Roanoke. Of course the number wasn't zero during the revolution period but to say early america was a multicultural project is laughable. It was an anglo protestant project.

they had a strong contribution in building up the Southern economy

This isn't true. Read and watch the data presented by Alt Hype. Paying cheap irish would have been more profitable. Blacks were farm equipment at best and not very efficient or profitable equipment either. For every educated northern black there were 100 sub 70 IQ slaves in the south. For every Frederick Douglas there were 10k domestics and agriculturalists. I've literally read multiple threads where you have this information painfully presented to you Salos yet you continue to ignore the independent historical sources and spout liberal academic lies.

They don't have any connection to Africa

Except that they are all originally from Africa. Are you saying British and German americans have no connection to Europe? Listen, I'm fine if you're trying to make the argument you want north america to be an open free trade zone where everyone in the world can come and be a citizen but you need to be clear that's the claim you're making (rule 3). You also need to stop retconing history and acting like it was always some free trade zone. It absolutely wasn't and if it was then you need to provide the historical documentation proving otherwise. The dissident right has provided you with the sources of their arguments. Where are your sources to the contrary? There is a pyramid of debate here you must at least attempt to follow.

I would support giving Louisiana,Mississippi, Southern Alabama,Georgia,South Carolina,Northern Florida(aswell as cook county,wayne county and Baltimore) to Black Nationalists who would have dictatorial power to do whatever they want with a few limitations.

Ok so now you're making a balkanization argument. I'm fine with that but let's not use historical myth to argue that blacks should get those regions. In my opinion black should only get certain regions so that whites can get their own. I will not give blacks pieces of the south on some stupid argument that they earned it through hard work and perseverance. There's just very little evidence that that's the case. Whites were the sweat, brains, and brawn of anything resembling civilization in the south and it will quickly turn into a third world country when black nationalists take it over. In fact that's the main reason I want to give it to them. So they can destroy it, haitize it and we can take it back. Blacks turn everywhere they go into pre colonized Africa when left to their own devices. It doesn't make them bad or evil it's just what they are. We as whites, no matter how much hope or compassion we have for blacks can never turn them into civilized people. We can be like Jews and turn them into manipulated pets or cross breed them into semi civilized people but we can never make them fit into the type of societies we want to live in. Cross breeding will only delude our own lines. You can even genetically change African by breeding out certain traits but that's essentially genocide Salos and I'm not a genocidal maniac. Grappling with all these truths is race realism. It's a bitter pill for compassionate people that love civil society and disdain barbarity. That's the pill you have yet to swallow salos. All empires that have attempted to control or shape the Africans have ended up crushing their own civilization.

You may think this is unreasonable and what not but we need to compromise,

No I'm very much pro balkanization but only as a compromise to get the white ethnostate. I believe that only a true white ethnostate will secure an existence for white people and white children.

Black Americans are not going anywhere and would resist tooth and nail if we tried too

Some would but whites could easily have them gone in matter of months if we weren't divided by the poison pill of liberalism. We could even have them gone morally in a matter of a few decades using peaceful soft cleanse methods.

I'd say it is better to form a secret alliance with Black Nationalists for this offer.

I'm not against this but it was done before with GLR in the 60's and it didn't work then so I don't expect it to work now. Most black nationalists have too many Marxist infiltrators in the ranks. Black nationalists are not independent enough from Jews to make any real political moves in my opinion. That could changed though so I'm not totally opposed to it.
