 I'll not take this ot thread any further; but your argument seemed to
 be "I shouldn't have to care about the proper use of apostrophes as

 perhaps I have misunderstood your argument.  In either case I meant
 you no disrespect. 
My argument is considerably more concise, and limited to the specific issue of
"its" vs "it's", than what your statement would suggest; it's
there in my first reply.
