I got a kick out of that statement about the Asians. I had to get new specs and the two opticians who ran the place were Vietnamese. First names were Stephanie and Tiffany. Years ago I implemented some software at the Kaneohe Air Station in Hawaii and had to work past quitting time. When I told the Asian kid who was the computer operator, he said he'd have to inform his wife he'd be late. I waited for him to say something like "Hello, Shino? . . ." Instead, I heard "Hey Martha . . .". Another stereotype died that night.
I think the black comment is painted too broadly as I've known older black guys with regular names. When I was a kid in NYC in the '40s we used to kid guys whose names were "George Washington Jones" or "Abraham Lincoln Smith". I guess it was when a segment of them wanted to re-segregate themselves that they started making up off-the-wall names.
“making up off-the-wall names”
With the look and feel of real Africa.
