Nearly all scientists are black in movies now also. And usually the only happy couples presented are gay.
My first recollection of a brilliant Black engineer or scientist was Barney in Mission Impossible (1966).
They had a still photo of Barney holding a slide rule.
Most Americans under age 40 do not even know what a slide rule is!
Also, in current day USA TV ads, 50% of the couples are Black male/white female.
They do get one thing right - a solid majority of white males are not attracted to Black women.
The flip side of that, a solid majority of white males are clearly interested in Asian females, but most Asian women have very little interest in white males.
I live in a suburb of Seattle that is 40% Asian.
Asian/white couples here are almost all Asian male/white female.
