Black men are feared just for existing. There is no difference aside from skin color but centuries of societal prejudices, discrimination, stereotypes play into this fear. Society also determined the desirability of white women & them being the "beauty standard" needing to be protected at all cost.

Regarding the white woman, it’s a scientific fact that she evolved her unique features like blond and red hair, eye colors, etc., to be more attractive in the competition for mating during prehistoric times. If you put a typical White woman in some village in Africa people will go crazy for her

I disagree. Skin color is just one of many differences. Features and hair texture are also critical differences. Not to mention culture, history, and sense of civilization. I believe the beauty of the white woman is innate and not merely socially ingrained.
