Ok I'm gonna chime in with my thoughts, take this with a grain of salt.
I've thought about "The superiority of black men" thing for a while, pro sports like basketball, football, track and field, just to name a few, are dominated by black men. They're taller, more muscular, faster, you name it. My theory is that when there were black slaves, the conditions were ******* and only the strongest survived, its horrible I know, but its true, the slave owners would work them hard and the ones who worked the hardest made it, eventually through selective breeding of the hardiest slaves generation after generation, eventually all that was left was the strongest bloodlines, at least in America, so after centuries of this happening what we're left with now is still those genetically superior bloodlines. Things have changed, people have immigrated, interracial relationships have flourished, but thats my opinion on why there are so many superior black men in the world.
Now I'm not saying this is true, this is just a theory, and I'm also not saying that EVERY black man is superior, there are lots that are just average of course, but it's hard to argue against, right? Or am I way off base? lol
