It is discouraging when some one tends to make negative or corrective comments about something you have posted. If I don't care for something, I don't say anything. If someone has made a mistake in some information they have given, I just suggest the writer go to a thread where they can obtain their own information. It is not necessary to tear each other down. We are supposed to be family and therefore supportive of each other. Unfortunately, some people have to be correct about everything. This makes them "look good". Also there are many people who are unhappy and as the saying goes, "Misery loves company". One expression I read a long time ago was from the old "Ann Landers column". She said, "You cannot sling mud without getting some on yourself". And, I love that expression.
