This feels like trying to over-explain something that is super obvious.
Next time you are in an international airport just people watch. Nothing more jarring than watching an African get off the plane for the first time and see their first white woman in the wild. No matter how the white woman looks, its like they've seen perfection.
White men have dominated the world we live in, and by default have turned their women into the standard of beauty. They can walk around with stank attitudes, they can have questionable hygiene, they can have nothing going on and it would be fine. White women means something to guys just by virtue of being white. They're a prize. Same way Eboni K Williams types will demand you or me own a trucking company, but would most likely bust oit open for a white boy who drives trucks if he had "Swag" and gave her the time of day.
