25 Rules of Disinformation
I think this web site will answer part of your question. Quite a few posters don't come here to play nice. They come here to draw a line in the sand and try to push you back to lose yardage, just like the game of football. If you were traveling with these folks on a cross-country trip by car and one tire went flat and you brought up the topic, they would tell you to shut up, tell you they know better and if you don't like the car get out and walk to Miami. But to recognize a defect, stop the car and get it fixed would be too much work. So instead they tell you there is no problem, they rely on some of the 25 Rules (web site) to put you down and keep right on driving with a flat tire or a broken o-line.
