I understand what you are saying. I'm saying that they might actually have significant education and still be a loon. My hubby is a mechanical engineer. One of his very educated co-workers thinks he is going to live on Mars soon. One would think with his degrees ect. that he would clue in. Don't discount having a degree or education as an immunity against being a loon.
