But the ignorant like to bring it up as if it's relevant. Blacks in this country have had little recourse but to identify with their visible attribute, almost as a defense mechanism...since the minute racist whites saw them THEY immediately declared them 'black', no matter how dark or light.
I find that and the old 'one drop' laws particularly offensive. Traces back to a MASH episode during my childhood I think, when they discussed black people dying because they werent admitted to 'white only' hospitals and were, in that case, not given blood transfusions to save their lives.
Hence the old expression, a "compliment"....you are 'passin', meaning you could pass for white. It always made me sick to my stomach to hear it and read it after that as a kid...and adult.
