Black woman disowned her Black mother because of the color of her skin. SMH!

A friend on FB posted this yesterday. She is a black woman herself. She was hopping mad about this. Initially, I could understand her reaction as I shared it too. Then as I watched this unfold, it literally broke my heart to see this story - for both parties. For me, the overriding feeling was sadness. I can't even imagine how someone could be in so much fear, pain, or both, to totally adopt a different ethnic background and live their lives as a lie. I wanted to be angry for her mother, but after seeing what her mother said to her, all I can say is I hope this will encourage her to change her behavior and her feelings towards her ethnic heritage.

After some conversations here on RP I wondered if this is more common a situation than I'm aware of, or what others think about it? I probably would never have seen this if it weren't posted on FB, but it's really been bugging me since yesterday so I thought I would seek opinions here.
