I do not know you, Mr. Harris.  I don't even wish, for any particular
reason, to know you Mr. Harris.  But I do wonder at the possibility that
your objection to the term "black water tank" is truly based on personal
belief.  More's the pity.

The term "black water" has been in use for centuries to describe water
which is impure, thus unsafe to drink.  Please note that the contrary of
black water is not "white water."  We all recognize the term "white
water" as representing the most exciting form of river travel.

Mr. Harris, there can be no racial pejorative associated with the term
"black water."  It is simply water unfit to drink, generally containing
sewerage.  Similar nominally ancient language include the term
"sinistre" (evil or sinister) in Italian, meaning (now) nothing more
than moving to the left, or being left-handed.

If we were to carry your thesis to its logical conclusion, we would be
obliged to refrain from using phrases such as "a chink in the armor" or
"a nip in the air," and also do away with the brand "Spic and Span."  As
well as "offending" Chinese, Japanese and Mexicans, we would need to
find some word other than "kraut" to complete the noun "sauerkraut"
(Germans) and find a new name for frogs (lest we offend the
French...who, incidentally are easily offended anyway).

I wonder if the fact that many Americans of African descent refer to
themselves as being black, or as blacks, carries any weight in your
thinking (do I loathe those hyphenated-American names, particularly
Cuban-American).

And don't call me a "gringo."  I will be mortally offended.

Unless you like sucking on a hose, there's nothing gay about this
thread.  Are you that homophobic?

Must be frustrating for you, thinking about all this lubricant going
to waste . . .
