Her biggest problem is she lurks mostly on extremist right-wing channels -- she lives in a bubble. Her bubble is a base who only get off on hate-filled racist and mysoginistic chatter. They are the type we call domestic terrorists. So, for her, when you are being reminded every day that part of you needs to die, it makes her depressed. But it's a strange depression because despite being hated by this group she desperately wants to be loved by them -- recall her dream guy would be an extremist white supremacist -- so naturally her only course of action, due to cognitive dissonance, is to rant on the parts of herself she hates -- the stuff she views as not wholly white.
She talked about this on stream once. She mentioned her mother, who is black was also racist (towards her own ethnicity) and hated herself and was severely depressed. Her mother would do things like wear blue contact lenses and skin bleach. Brittany said that rubbed off on her a lot and she essentially became her mother. Hating herself too and being more drawn to white supremacists, taking part in racist rallies (recall she was part of the infamous Charlottesville racist rally to be accepted by her dream men).
Brittany is not a good person. And never will be. She represents the worst of humanity.
