Nothing.
You imply I would somehow be upset at the hypothetical scenario in which my skin overnight turns a darker shade, this is because you are a simple minded racist bigot. If I somehow turned African-America(not black chud, that's insulting) I would be absolutely thrilled that I can season my food unlike ytbois and have a culture that built the pyramids (it's true racist, Katt Williams said so) and I would have a picture of the 44th president of America Barrack Obama, Al Sharpton and St. George Perry Floyd hung up on my wall and with pride. Frankly how dare you suggest that anyone would be upset that they would be African-American, grow up racist.
