Because AAs are so mixed up with diff ethnicities that no one would rally know. For instance, I'm mixed with Guinean, ghanian, Cherokee Indian, English, and God knows what else. I don't look African that's for sure. Not with a Native American nose, cheekbones, caucasian bi lobed chin, and a light complexion---my own mom thought I was Paki, when she saw me drive my car. So what language do you suggest I learn Swede? Cause I don't know which Guinean or Ghanian ethnic group, most Cherokee speak English now.
