People are mad over a DNA test

Just your usual celebrity drama! Demi Lovato posted recent DNA test results and people were attacking her and saying rude things bc she mentioned how she was 1% African as well.
I have noooo idea why people are mad that she posted DNA results, but I wanted to know what you all thought of the whole situation! Are people's rude remarks justified, or are they just making a big deal over nothing?
