Meh. As a black man, I find what she is doing to be stupid and unintentionally offensive and counter productive, and entirely unrelated to LGBT issues. The fight against racism hinges on the concept that race is an irrelevant social concept and all people have inherent egalitarian value regardless of how much melatonin is in your skin.
Gender and race are entirely different. A man wishing to be a woman is practically desiring an entirely new chemical make up and "reproductive" organ system. Wanting to be another race though, is just retarded counterproductive thinking. You shouldn't "feel black", because objectively, all races are equal since the concept of race is again meaningless. By desiring to be a different race, you aren't preaching equality, you are unwittingly acknowledging that there is an objective inequality between races, which defeats the entire purpose of the fight for equal rights for all.
This woman is well intentioned, but very stupid, and may have possibly set a dangerous precedent. I can understand admiring black culture, but lying about undergoing struggles stereotypical of blacks and posing as black to get a scholarship like a female Soul Man seems a bit extreme and arguably unintentionally racist. If she really wanted to feel equal to blacks, it involves not seeing an objective difference between black and white and not seeing race as a barrier, which she clearly did since she felt she had to change herself and lie to overcome it.
It's like trying to ally with the Chinese government by posing as Fu Manchu. It just defeats the purpose.
