Not to play semantics, but in my book the ad's not a hit piece. To me that implies an unfair characterization, and this ad ain't that. :-)
The ad is a hit piece(according to the rats). Remember anytime you tell the truth, without holding back, you destroy the rats. They will claim foul anytime "unfiltered" truth sees the light of day. They demand that everything be filtered or spun. We need to keep it up.
