Please with the so and so is “half Dominican”. OP asked about Dominicans period.
Growing up in NYC, Dominicans mainly stayed with their culture of music of Bachata and Merengue, and didn’t seek to adapt to Black music. Puerto Rock youth had a different relationship with Black youth, a tight relationship of respect to each other’s culture of music. It’s unexplainable. Also, where I was living, PR and DR kids didn’t mess with each other, and since PR gravitated toward the Black man, I guess DR were like
“Mi no Black papi”, and kept to themselves. Hip hop wasn’t a DR thing for some odd reason. Back then PR treated DR like Jamaicans used to treated Haitians. Like they were lower, but that’s another story.
