Mr. Cruz that's a silly assumption. Black people referring to themselves as African-American doesn't mean they have a problem accepting the fact that they are black. That's far from the truth. That's just one of the many titles that we and others use to describe us: black, African-American, Afro-American, negro, etc. Over the years, it just came to be accepted (African-American) as the appropriate/PC title since we are descendents from Africa. But hell, if you want to look at it in a broader sense, all of us in America can call ourselves African-Americans because life started in Africa.
I, for one, say that I am black. But, as I was growing up, when filling out application forms, the only title available for black people was "African-American" (which was initially Afro-American). So, some black people refer to themselves as African-Americans because that is what has become accepted, what they have been taught to call themselves, and how they identify with their heritage. So please, let's erase that little bit of ignorance. I have no issue with referring to myself as black...it's a powerful thing, and I embrace it fully as many other people who refer to themselves as African-Americans.
