PM for you. I've had the poster you responded to (not even going to type it's name) blocked for weeks and didn't even bother to go back and read the tripe it's posted THIS time, but your responses were eloquent and reflected what I believe most of us here feel.
In any situation, a devils advocate is a good idea to keep us grounded and objective, but when time and again, the same bilge water is brought up, refuted, and dismissed, it's just plain irritating.
The MM's surely want us to take our eyes off the prize to chase these meaningless distractions around the yard. IMO, the best reaction is the ignore button, unless it's a response like yours, not arguing with them, but shining a light on their triviality.
Remember Charlie Brown's teacher...wah wah wahwah wah...
Just my sentiment.
Go CDIV!
