Apparently, you are one of those that would rather talk than listen, i.e.
rather than read carefully, before putting your foot in your mouth!  You are
off on a tangent unrelated to my point which you quote as your introduction.

Further, apparently you must feel that your argument is weak enough to
require the additon of personal put downs along the way.  Additionally, you
have not copied your reply to the list to which my statements were made, nor
have I witnesed your past participation in this list.  Smile, shape up, and
join in!
