It seems to me that lack of political experience is a fair enough criticism of Ben Carson. There are negotiating skills that make politicians who have honed them more effective in bringing about the goals that they have set out for themselves. A comparison of the way that Bill Clinton was able to deal with Congress and move things forward compared to how a rather junior politician such as Obama has performed very poorly in that regard demonstrate that there are definite skills involved, and experience is an asset.
Another possible criticism could be made by comparing Carson to Reagan. Reagan had spent a lifetime studying the communist system and came to the job prepared to do battle for the American way. He had a vision and a reason for wanting the presidency. While Carson certainly appreciates the America that has allowed him to rise to the top, it is unclear of what his unique vision is that he requires the office of presidency in order to put them forth and bring that dream to fruition.
Those kinds of criticisms are authentic criticisms of Ben Carson. These are the kinds of arguments and criticisms that any potential president needs to counter in order to be deemed worthy and an asset to the office of presidency.
So far the arguments about West Point and pyramids are as trivial as the people who are putting forth this kind of fluff.
It is rather pathetic actually to see how low and inane political discussion in America has descended. These are non serious discussions of a people who no longer take the role of America in the world seriously.
