An aspect of BNWO that I love besides the obvious black supremacy in size is the black sperm count supremacy.
(sperm count is the # of sperms a man can produce btw)
Under BNWO, White men's average sperm count has been decreasing year by year. Meanwhile, in BNWO, black men's sperm would not only continuously grow up to millions, billions, and trillions, but the individual sperm qualities would evolve as well.
In the end, black sperm count would grow up to the point where it's impossible for a whiteboi to ever compete. And a single black sperm would outperform a horde of white cuck sperm as well.
