If I were a White man, I would not risk moving to the DR, that is just my opinion. I would aim for Uruguay or Chile, because those countries have large populations which are of European descent. I would also consider Argentina but their government keeps making economic mistakes. I'm being a "racial realist." Do you want to know why I'm saying this? I will give you guys and example: LIBYA.
Libya has a majority Arab/Bedouin population. When Gaddafi was in power, he was tolerant of Blacks and allowed them to settle there. Guess what? Now that Gaddafi has been overthrow, the new regime has been targeting Black Libyasn for genocide. You can go Google it, it has been all over the news. They are killing, torturing, and throwing Blacks in prison. What is the moral of the story? When a society collapse, being a minority in that society is dangerous. I've warned Blacks against relocating to European countries because, if the EU collapses, and Europeans revert back to nationalism, there could be a backlash against minorities living in those countries. Even a Greek Olympian got kicked out of the Olympics because she made a negative comment regarding all the Blacks living in her country. Europeans could easily turn on the Blacks that are living in there nations, just as Hitler did the Jews. Likewise, Dominicans could do the same thing. This is why if I were White I'd aim for Argentina, Chile, Uruguay, and not the DR. Since I'm Black, I have no desire to live in any of these countries for the same reasons.
You forget that "Blacks" have been in Libya since forever..... as is for millenia - It is in Africa after all - the first occupants were "Black" ...then came the others white/brown Arabs, etc......
The Arab and Asiatic foreign fighters brought in to create"revolution" have always had animus towards Black Africans and in particulr Quaddafi's fondness and acceptance of his and Libya's "Blackness"....but your point is well taken.
I think the Libya example might be more illustrative of what could happen if there is a major collapse in the DR. Dominicans and most Latins absolutely worship "White People" - they spend much of their time and cultural life negating all African and exalting all European. If there is a collapse, it is the unambiguously black Dominicans and Haitians who will have the problem...(see Trujillo). the "White" will be perfectly fine ...... Dominicans regardless of complexion want to be them or love them too much and will not overly harm them
