And quite frankly you really shouldn't be on here telling Black women how to feel about what she did because YOU feel a certain way. Rachel wasn't lying to and impersonating someone who looked like you or claiming your culture as her own.
You also don't get to tell Black women (the most demonized and vilified people in American culture) how to feel about it, understand what she did, or react to what she did. If she was impersonating an Asian woman I'd leave it alone, because it doesn't concern anything in my life, and I'd let Asian women react how they see fit and not speak for them or call them crazy for feeling a certain way. She chose to pretend to be something I was born as, and I can't just put on or take off because I feel like something: a Black American woman. Being an actual Black woman involves more than just a change of skin color.
If you'd bothered to have a conversation with some Black women you would find we are all of a variety of opinions on her. I, for example, don't hate her. I pity her for her self hatred, and in not being comfortable in her own body. She wanted to be an identity she wasn't born as, wasn't ever treated as, and didn't experience as a child or young woman. For her, my race and culture was something she could appropriate to feel good about herself, and i felt compassion for her. I actually appreciate that she put in the work of being anti-racist though, while other Black women just don't care and some others won't forgive her for any of it.
