As a mod I have a responsibility to read every post in it's entirety. You are correct about arguing with crazy folk. I don't feel or believe that is the case with either Posada or my good friend Nicky. Both tend to be contrarians and often comment for no other reason than balance and to elicit a response. I completely disagree most of the time. However sometimes it's important to fact check or at a minimum point out inconsistency.
I have been a member of PBS since the early 80's.
