who is black and who is not

To me these girls were all black I don’t know why they are saying that they don’t know what they are considered. How I look at is that if you have a parent that is anything other than white. Then you are not white, you are what the other parents race. The reason I think that is because everybody here is white like if you say something other white its more interesting. Its like a surprise that people find out that your not white and they though you were. It’s not a big deal to me what other people think of me or what I look like. More important is what you consider your self or not what the government considers you are.
