If I were asked to name the least "arrogant" person who posts regularly, it would be SGE......and for the following reasons:
1. He has always invited critics to confront him.
2. He has always recognized flaws in his logic if they are pointed out.
3. He is not insulting to his detractors.........unless they really cross the line. Even then, his criticism is honest.
4. His regular sign-off is an admission that he "knows nuttin." None of his detractors have ever admitted to "knowin'nuttin." That sign-off is a perfect example of a man who is self-confidant , but willing to be challenged.
IMO, SGE has proven himself to be intelligent, knowledgeable, and a valuable asset in this forum.
Arrogant? I don't think so.
