She has no integrity, period. She tried to co-op a very specific identifier: transracial, which is only applicable to those who are adopted by another race. Her own sibling (who is a transracial adoptee) called her out on that in an interview. She's never grown up in the foster care system, she's never been black, she doesn't get to use that term.
Then she attempted to conflate her masquerade with being transgender, which implies that trans people are lying about their own identity. She's stepping on actual minorities.
If she just said, I'm a white woman from the start, she'd still have her job at the NAACP, maybe still be a college professor, and wouldn't have garnered such a scathing opinion. I don't have any sympathy for her.
Remember that time the world bent over backwards trying to convince itself that this was called "transracialism" just so a single white woman could do whatever she wanted?
It's about to happen again.
Transracial is a valid term. It's not for a white woman who puts on blackface though. She and her supporters have misappropriated the term.
