This is making me wonder if Rachel Dolezal started claiming she was a person of colour out of fear of rejection by the community. This would be similar to a pre-transition transperson, fearing the social consequences of being true to themselves.
It might just be my biases, but I feel a bit happier with that than with the suggestions of transracial going round social media, which feels belittling both to transpeople and people of colour. It’s not good, but if I am correct I can at least start to understand why she did it.
