Why is everyone so angry? If it is so apparent that someone is regurgitating something they heard or made up, then ignore it. You never know, something amidst that garbage, may be something useful. It seems to be a seniority thing, you can't talk about a topic, only ask questions because it is impossible for you possibly know anything. As you may have guessed, I am a new diver. I won't preach anything as people without experience should'nt, but different perspectives on topics should be entertained. Here is an example of where I am coming from. Here on Long Island, we have low overpasses that 18 wheelers cannot pass under and on occasion, one tries and gets stuck. One particular incident, they could'nt pull the truck loose. It was young kid that said to the emergency people "let the air out of the tires"! Well it worked. It worked without any prior rescue or mechanical experience, just common sense. So before you rag on new people, realize not all are spewing bs they have heard. Listen to opinions and decide what is the junk.
