African-Americans. Aside from products of mixed marriages and generations away from any African heritage, what is their connection to Africa?
Roots.
If I recall correctly, decades ago, Jesse Jackson urged us all to refer to black/Negro people, as “African Americans”, and the description caught on.
Such people are African-Americans in the same manner as many Americans can be said to be “European-Americans”, based on the ancestral home of their ancestors who came to America.
