My dad had Black Like Me on his bookshelf, as a psychologist. It wasn't merely professional, either. Our Irish ancestry has a darker skin tone than normal, but still 'white', and afro-textured black hair. In the service at the end of WWII he was denied restrooms in Georgia.
I find the inference that posing as black for discovery is just another form of blackface to be very interesting, and a tell of racism, realized or not, within the speaker themself. It's also interesting see how people want to form the line of color on a spectrum that is largely seamless.
