Thank you @krazykrista. (Not-so-krazy!) Much of the crux of what you are saying reflects back on a person's self-confidence. Those who are filled with self-doubt and low self-esteem, cannot bear to risk not being at the top of the heap. They erroneously believe that being right adds validity to who they are. And usually, the only way they feel "right" is to make you "wrong." Sad, but true.
