BTW, being HIV positive and urinating on the pile would be little
different than someone not infected doing the same.

Nope, it wouldn't be "little different", it would be NO different. The
virus doesn't live in air.

You are incorrect. Most individuals who are HIV positive are also on a
cocktail of medications to stay alive. Therefore the urine would not be the
same -- there would be a variety of chemicals present that are not present
in the urine of those not infected. Furthermore, each individual would
likely not have the same biological processes, eating habits, and other
factors that affect urine content. Ergo the statement that the two would be
little different.

Semantics aside, we're saying the same thing -- this aspect of the thread is
purely idiotic.
