I'll start by asking you - What makes a person in your mind "black" ?
Is it merely their skin color that defines the term and nothing more ?
If a person has dark colored skin, and they have other defining body features that make up their entire model, then does their skin color alone define them ?
Most blacks would say "NO" it does not define them.
Most blacks or dark colored people see themselves as being part of a great movement in America, and they don't let the movement define them totally as being black or dark colored skin, otherwise as if that means something when it doesn't.
