I find it pretty funny (funny clarified as odd, not haha) that you would jump to the conclusion that I meant blacks were incapable of swimming, especially when I specified a certain part of the country.
I find it odd that you think I jumped to a conclusion. What I have done, rather, is show you that what you have said can be taken in more than one way, by providing a specific response to a specific possible meaning for your sentence...and you realize this, because you posted about it subsequently.
Your specificity about the South is insignificant because you stated that you couldn't "vouch for the rest of the country."
I'm in error because you used the word "most," which I ignored in my initial response.
