Is this person implying that black people aren't familiar with female anatomy?

Yes.

Just to add my two cents, the film was about overcoming a nervous condition that caused him to stutter. It had little, if anything, to do with anyone's right to be heard or not heard. I understand that the post was meant to be inspirational and whatnot but the context of this is very important

The only thing sports does is prove that one team or person does nothing of importance more capably than another person or team. Without an audience any sports event becomes largely pointless. People pay money to watch something they are not actively a part of purely as a form of entertainment. The only reason people are so quick to demonise sex workers is because society says it's bad and because it's considered to be easy work even though it's really not. If we're going to demonise people for using their bodies to make money, we have to at least demonise EVERY ONE using their bodies to make money

They don't actually contribute anything to society and someone has definitely fapped to a picture of Christiano Ronaldo

I'm assuming no one mentioned it because they either didn't see it or because it's such an inconsequential detail that doesn't affect anyone in any way that it didn't warrant getting mentioned.
