sprog, you are correct. And mongo, contrary to what you might believe, I don't really disagree with you. You keep mentioning things like "Work Area", and basically I agree that that is not the place to really be talking those things. However, sprog I know where you're coming from. I retired at F.E. Warren. (I still live here). Spent many of hours under the MAF while SLFCS and other things were being re-wired. All sorts of topics get talked about down under. And there's nothing wrong with that.
Just like enlisted personnel in their dormitory. It it common and perfectly normal, for junior enlisted 17-20 year olds, to talk about their supervisors, officers, and even their commanding officer. It's not uncommon for them to bad mouth these people among their peers. It's part of their growing process. It's part of their maturing. It's part of their venting. And by doing this, they realize that they aren't the only one who thinks they have it like crap sometimes. And they also hear other experiences that put things into a different perspective. "hmmm, maybe my boss, commander, OIC, etc... isn't such a dick". This is just an example of where it's perfectly normal and acceptable to bad mouth your chain of command. And this is healthy. You can't tell military members that they aren't ever allowed to discuss politics, religion, sex, dissatisfaction, etc... among themselves. You can't just say: "Keep your complaints to yourselves". That's not healthy. You need to be able to vent. And in the military, as much as our family is part of the military family, I'm not going to go home and vent to my wife. I'm going to do such things at the club, in the field, and other places with my peers and co-workers. I'm not going to do it at the local downtown bar, Chili's Restaurant, my son's school PTA meeting, etc...
But you don't do it "on-duty" normally. You don't do it in a public arena where your intentions can be misinterpreted. You don't do it in front of reporters. You can't live an emotion free life where you can't vent dissatisfaction, or speak your mind. You just have to know when and where. And this is where General McCrystal messed up. He allowed his personal dissatisfaction, that he was venting, to be made public. That's no cool.
