While there is no extra muscle, it is factually true that people of West African descent tend to have more fast twitch muscle fibers which is a pretty big advantage in many sports.

This is likely why the myth of the extra muscle originated.

This was taught to me in grade school. I feel pretty betrayed.

Suffice it to say, I found it dubious even as a child and as an adult, learned better, but WTF.

I remember my friend's mom telling me this when I was like 6 and then I told my mom what I learned and she told me not to listen to that lady.

My dad told me as a kid black folks have more fast-twitch muscle fibers.

Classic fascist narrative: The enemy is both strong and dangerous, and weak and dumb.

Have you ever tried to steal a base in a full length robe?

Here's his quote:

The black is a better athlete to begin with, because he's been bred to be that way. Because of his high thighs and big thighs that goes up into his back. And they can jump higher and run faster because of their bigger thighs. And he's bred to be the better athlete because this goes back all the way to the Civil War, when, during the slave trading, the big, the owner, the slave owner would breed his big black to his big woman so that he could have uh big black kid, see. That's where it all started!

Racist. Definitely racist.

I'm not trying to be pedantic, but I want to draw your attention to what you said about being unsure about the person's motives. If a person says something like "they (a group of people) are bred different" then that's racist. It doesn't matter if the person is a bigot or openly hates people for their skin color or not; that kind of belief is eugenics and is a racist belief.

Good people, well-intentioned people, can be and are racists, because they are raised with certain ideas and beliefs that are rooted in racism. The things that pop into heir head are racist because they haven't taken time to look into their own beliefs and understand where they come from, to de-racialize their thinking.

Or, you know, they're bigots and like having racist thoughts because it serves the bigotry, but that's a different problem.

I think someone who is forced to do hard labor since birth of course is gonna be stronger than a master who can't wipe his own ass without 15 servants helping him, so they gotta think blacks are naturally stronger.

The famous example you're thinking of is Jimmy Snyder, aka Jimmy the Greek, a sports commentator and sports betting expert who used to work for CBS sports. He was interviewed as part of a series about civil rights in the US, and the interviewer was sort of expecting him to say something pleasant about black folks' success in athletics opening doors for education and leadership, etc.

Instead he made some pretty astonishing claims that were intensely racist.

If you’re English, then you misspelt the word ‘colour’.

Same in the US now, but in our case it's because although 'people' is clearly self-evident if you're talking about a person/people, during the time of segregation those were the terms used - coloreds & whites. Whites Only Water Fountain. Whites Only Bathroom. Coloreds at the back of the bus, only Whites up front.
