that's because people like YOU have offered nothing productive to add to the discourse in any meaningful way..
All you have done (rather successfully I may add) is troll it with your incessant drivel and constant deflections.
This thread was started with a serious question, but as usual you have managed to derail it with your mindless bickering and half-witted, smarmy remarks.
Kudos to you for winning the AN tosser of the day award!
