I agree that this exists, an anti-Haitian sentiment. The political history runs deep.
At the same time, I have to say that it’s often different on a one-to-one basis. There are several Haitians who have lived in our campo area awhile. They’re accepted, they date/live with Dominicans and work with them.
There is a difference between being anti-Haitian because you hate the Haitians vs being anti-Haitian because you don't agree with the current migration policy (which seems there is no real migration policy in practice.) The second one will have anti-Haitian feelings directed towards Dominican politicians (for obvious reasons) but have no problem with Haitian individuals. The first one the hate doesn't permit them to treat a Haitian except in situations where you are in a higher position (wachiman vs resident of the building he "protects.")
This happen a few years ago when I was at the family house of a then woman from La Vega I was beginning to date. There were three things.
First, the entire family was composed of whites and light skin that are still considered white by many in the DR. The woman I was starting to date responded to a comment I made about one of her cousins who brought to the house her boyfriend that looks like a black man here, there, everywhere. He was the darkest person there to the point that if you were ask who is so-and-so they are suppose take something to, you would say "el moreno" and everyone would know who it is, no "which one" question. Well, she told me that that was one of the few times she took him to that house and then the bomb, she said that the first time she took him to the house, no one knew her boyfriend was a black man until they saw him. During the entire time they were there he was treated with no difference from anyone else. However, one they left the grandmother made a face and said "ese negro" and then another face of disapproval. The joke was that her grandmother wasn't entirely well, but they said "para eso sí está bien."
The second time was another day seversl of her family members and myself were in the zaguan simply talking nonsense. Then the conversation took a turn regarding someone they knew since he was a kid. He was born very light skin but with time bevame very dark mostly due to extendive sun exposure. This was the exact words of one of her aunts: "qué pasó con ***, él era bonito y ahora parece un haitiano,
ay no." The following day in the morning I was at the house and she was on the edge of the zaguan speaking with seversl of the Haitian men that worked in a small business they have right on the same property, but apart from the house. She wasn't giving them orders or anything, they simply stop as they arrive to greet "la doña" as she was in the zaguan and you have to pass by the side of that to reach the place where they would work. There I was watching that scene when the day before she made it clear she doesn't like the color of the dark Haitians.
Not related to what happen at the house at that time, but the convo included the same aunt from before and somehow the topic touched was wearing sun screen. She asks me if I wear sun screen and I said I usually don't. Her literall response: "ay no, eso no se puede. Yo me junto uno que me paso el día entero en la playa y no se me cambia nada" pointing at her arm, which in reality to her skin color which by all accounts is white. I take the issue there was not wearing sun screen for pretection from the sun, but rather to avoid getting a tan.
That's only some ocassions while visiting that family, but I have many other situations that through the years I have seen even within my own family, but never to the level as explained here. From an aunt-by-law saying that one of her friends said that thank God the son of her daughter has her color, because "la familia de él sí es prieta" and then my aunt-in-law was laughing at that and not a light laugh. She was the only one laughing, to the point that my auncle who is her husband responded "muchacha" and that was that. That happened at my uncle's house in Puerto Plata. There are many other examples.
That's not to say there is a huge issue that doesn't allow dark skin people into the family, but there is something "light" in the air, so to speak.
