Sad that we have to think about this, but people would have never accepted michelle with a fro or even a 3c curl.
I don't know that we can know this. 2 years ago people would have said "the U.S. would never accept a black man as president, especially if his name was "barack HUSSEIN obama", yet they did. Considering they accepted that, I think a that they would accept a woman with short cut curly hair is not that much of a stretch.
