Everyone on Free Republic are qualified to be the Secretary of Defense. Not everyone gets a chance to serve in that position, but they are ready. And, they have opinions of how to do it, even if they have never heard of the Transportation Corps who have the mission of moving army men and their stuff from Point A to Point by land, water, and air. I used to have a shoe box where I kept my army men and all of their stuff, my own Transportation Corps.
It would not be Free Republic without everyone being qualified in everything, at least in their own minds. In my experience, a few people weighing in, on whatever, actually are qualified.
An old joke about rabbis(that I actually once heard from a rabbi) is that whenever 3 rabbis get in a theological argument, you will hear five different opinions. This applies to FR, as well.
