Not Nice
I see that a lot in the last two decades, but I think that's a little different. Rap music made it very fashionable to be Black, which ultimately was a positive for society.
If you're in a mixed race relationship it's common to take on some of the appearances and dialects. Way back in the 70's we had mixed race neighbors. He was a keyboard player in a band and she was a blond haired blue eyed housewife who sounded exactly like the woman you describe above.
Back then it was unusual. Today it's common.
On the flip side, black people who enunciate, and sound 'white' are criticized in much the same fashion in their own community.
Very much so. My DIL has fretted on her social media page about that. She is Black, well-educated (she has a masters in business and a BS in industrial engineering). She typically "sounds White." Apparently she's had comments from Black friends/acquaintances criticizing her for that. It's interesting that my g-son, who is now 22, used to sound like a typical White kid. But since his early teens, he sounds like a typical Black kid. His gf and most of his friends are Black. He has decided where he wants to be in his world of White and Black, and is happy there. Good for him!!
