We must learn to respect one another on a forum like this. I don't think people should be insulted for making a post. Referring to someone as dumb or fool just because of a post that you do not agree with is totally out of order. Rather than criticizing a post and insulting someone, why not just ignore. If everyone is an expert then who will be a novice? Mind you, you only know what you know, you don't know it all. Be polite.
