I say whatever floats one boat.
First generation Dominicans in the US, especially the black ones, like to call themself anything but American even though that's clearly what they are. It's like it makes them special or something so I say whatever.
I met a "dominican" guy. He was born in St. Paul MN to Dominican parents. Didn't know a lick of spanish, had never visited the DR before and probably couldn't find it on a map but when I called him black he says, "I'm not black, I'm Dominican" I'm thinking but you don't even know where the DR is.
I'd consider him a poser, a faker. Someone who just "wants" to be different.
But I met a girl on a message board who was born in NYC to Dominican parents, she speaks the language, visits all the time, knows the people, the culture, the customs... She has a strong interest in her parent's homeland and has made it her own. I say she's "real"
I don't know why so much controversy surrounds Dominians, PR's, Cubans about their "realness". Like first born generations from Jamaica, Trinidad, Bahamas, etc.. don't have all that baggage. You never hear them saying, I'm not black, I'm Jamaican, or I'm not American I'm Bohemian, etc... They acclimate to American society and embrace it just fine. But Dominicans...good lord, it's the strangest thing.
But my position is that the beauty of America is that you can be anything you want to be. So when Dominicans born in the US start spewing that "I'm Dominican" stuff even though they probably can't spell "Dominican" I just say whatever.
