Let me give you the perspective from inside the uniform.
1) As a segment of society, Soldiers are no different that any other large organization. I am an Army Reservist, so I supervise civilians in my "normal" job and Soldiers when I am in a duty status. As a segment of the population, civilian employees have just as many issues with work ethic, ability to interact with people, etc. That's why just as many civilian employees get fired for their misdeeds every day as Soldiers go to jail, get discharged, or get punished for their offenses.
2) The military has it's own culture like any large organization does. You are attacking the culture itself with your generalizations. That's fine, but understand the difference between opinions, facts, and reality. You don't seem to be able to discern the difference between them in any meaningful way. I can assure you that the military culture looks out on civilian society and draws their own conclusions as well. Eventually though, given time, when they (the people in one or the other culture) are forced into that other culture, they adapt and assimilate whether you believe that or not. Military members are fully functional human beings and only very few of us have a propensity or desire to commit violence and even then, probably not at a rate above that of the normal society at large. Feel free to provide statistics that shows different. I promise that for every Soldier that roughs up a foreign national on the streets of some foreign land, there's a guy in your office that just beat the shit out of his own kids or wife last night to match it.
3) The heart of your angst and issues should be targeted toward the public at large. It is a very, VERY uncomfortable feeling for me and other military members to walk through an airport in uniform and be publicly revered and coddled for our service. You would have us believe that we are something akin to a professional wrestler who steps into the public and demands attention and reverence through being overtly loud or demanding this treatment. We don't. We wear what we are told to wear in conjunction with the rules that we operate under. There is a mandate that requires Soldiers to wear their uniform during official travel. There is a mandate to wear uniforms for certain public events that more often than not, the event organizers or the patrons demand our presence at. We certainly don't go out to NASCAR events and demand that we be there to get a standing ovation. The public wants that, they ask for it, they demand it and reluctantly, we are told to participate. Of course, that comes with public service as well, the taxpayer deserves to see what they are paying for and supporting, it is what it is.
I can tell you flat out that most Soldiers cringe at the notion of shaking dozens of hands in airports or being lauded in public establishments when all we want to do is our job. I don't ask to have my meals paid for when I'm on official business in uniform, but it happens far too often in my opinion. But then, I've realized that those things are less for me as a Soldier and more for the person committing the act so they can feel they contribute to our nation's security in some way. It's for them to feel good about themselves more than anything.
4) It is estimated that only about 1-2% of the people in this country will commit to military service in their lifetimes. Because of that, we are a limited resource, to most people, we are an anomaly in their lives. I forget because I work on an Army installation every day, that most Americans rarely even see a Soldier in person unless they are in an airport or similar place. If I'm driving cross country on business and stop somewhere to get gas, it's uncomfortable to be pointed at and talked about but it happens. Why? Because when you make up such a small part of the population, you are a rare sight outside your organizational area. That's not our fault, but you want to pin that on us for some reason and you're wrong for doing it.
In a similar vain, because only 1-2% of us will ever do the hard job of the military, most people have resigned themselves to never being able to do it themselves. It may be choice, it may be fate, it may be destiny that they can't do the job, but whatever it is, they respect what we do because they can't or won't do it. Again, you pin that on us because we CHOSE to do it when very few others could or would. Instead you sit back and criticize us for our service and for the respect and reverence poured on us by the general public who likely harbors a twinge of guilt or respect because we do what they can't or won't do. Again, not our fault, we asked to do the job, we didn't ask for everyone else to put the burden of fame on us like has happened.
So, having said my piece, I can somewhat agree that the American public places far too much of their reverence and respect in us. Realize though that it's the masses doing this, not us demanding it. When we go out in the public and demand respect through coercion or force that is perpetrated directly by our government or our military, then you should come down on the service members for it. Until then, you're a misguided chump who can't assemble a complete thought over the internet.
