There is no physical reason that a negro cannot swim. Especially considering the physical shape many of them exhibit.
It’s mostly a mental thing.
I had a friend (Caucasian) who stated he couldn’t swim. Since we went to a local Lake to go fishing repeatedly, I had the opportunity to try and help him learn how to
swim.
He used the same excuse already posted in another comment. He said his bones were more dense than mine. So, I grabbed a boat anchor (metal bucket filled with concrete) and jumped in the water. Swam around carrying the bucket.
Finally, after watching him try to swim, I figured out what the problem was. On average, if you are treading water, the water will come up to the bottom of your chin or mouth.
HE was trying to paddle his arms to keep the water level somewhere in the middle of his chest. Of course, he couldn’t, and would start ‘sinking’ (in his view) and therefore the claim he couldn’t ‘swim’.
It is that ‘fear’ of the water getting near their mouths that make people think they can’t ‘swim’.
You can’t breat water! At least that’s my excuse.
