You just say blacks hate the cold. The only reason they are good athletes is because when you have to run from lions and tigers you get fast or eaten.
I feel like you're being racist against black folks. Do you really think black folks always run from tigers and lions?
Yes. It's because they are fast and strong that they survive the cold; they were running from tigers and lions.
You are being unfair to judge how blacks run and why they are so fast. I kind of believe it is just their hidden talent, most blacks have never even seen a real live wild animal. You might think you mean well with a compliment, but it is backhanded and not acceptable so stop.
Why is it so racist again?
It's racist because you think that black folks are primitive and they are constantly being hunted by tigers and lions, where in fact black folks live in the modern world just as you and me, so I think it's time to stop that prejudice and just be friendly and respectful towards your own human kind.
