The problem is, even in all of your responses (minus Chronic I think) you're all classifying all Black people as one group of people and I'm thinking that's it's the people who are considered "African American"."
Well, yeah? In America, as Chronic said, Black is synonymous with African-American. If a Dominican is called Black, I would say that it's inaccurate, because a Dominican may or may not be from Africa. When I address people as Black or African-American, I address them as such because it's politically right to say so. In my surroundings at work or in school, it's required. If I can't distinguish, then it's my fault, but shouldn't be taken as offensive. In the end, it's simply just another way of saying "THAT person" instead of pointing a finger, if that makes sense.
Africans are not Jamaicans are not Bahamians are not Dominicans are not Cubans are not African American but all can be considered Black.
Well, there are lots of gray areas with these "race labels". You have to understand, when people label you as Black, it's just another way of pinpointing you or identifying you as a person. If you refute the label, that is fine.
The thing here, and I wouldn't say problem because it's not, is that you don't even want to be addressed as Black or Dominican or African-American, but just American. That is just YOU, though. Generally speaking, people don't mind these labels; on the contrary, they take pride in it.
I mean, I know Blacks here who don't want to be called African-American because they can't even identify with the Africans that emigrated here recently and want there to be a difference. A Somalian who came here five years ago and a 5th century Black American are different, the Black friends would say, and I don't see why I wouldn't agree with that.
In the end, it's all about people's preferences. We have these labels because it makes it easier for identification and classification. In the end, that's what it's all about. I mean, race here is so sensitive that I know Philipinos who received scholarships intended for Blacks (Black scholarship) just because how the hell is a 50 year old white man going to tell a 16 year old dark kid that he's not Black?
