It shows Eastern NM and we have around 1% black and the area that they show in Texas doesn’t have huge populations of blacks.
It really makes no sense.
In the late 70’s, I lived in Boone NC and there was one black kid in the local high school. He didn’t have any choice but to date white girls. When he moved to “the flatlands” to go to college, he was amazed at that white girls refused to talk to him. Other black guys were amazed that he dated white girls in HS.
