I for one have never called anyone a liar at the board. I rely on verifiable facts and sometimes question phone calls to anonymous people, or unsubstantiated facts. I think all readers should question the validity of every post pro or con.
I do feel you ask others to do the work in your post. You seem to take a pessimist stance, that’s fairly easy to do. I have seen no verifiable DD you have produced? Why not post facts instead of questions? A little more difficult to accomplish, but something worth posting that the board would actually consider.
