I have two beefs.
1) if Glenn Beck was going to give us advice on what we can do to prepare for a hurricane, its his right to do so. but there was a lot of information that he papered over, and he focused only on his pet idea. and to me, that is kind of shitty that other peoples suffering becomes a pawn to advance a specific Glenn Beck agenda. why harp on food, but not flashlights?
2) I get his context. his word usage sucked though. there are a myriad of ways to convey to express what he wanted to without saying " blessing in disguise". he could have simply said " I would like to take this time to illustrate that having food stockpiles is important as supply disruption bs bs bs"
thats the nice part about language, you can get pretty damn precise if you want to. and if thats what he wanted to say, well....
