Actually TAM, some of the truthers have a moderate deal of respect for you (A JREF'er, imagine!) because you treated them with politeness. No one is ever going to believe anything (regardless of evidence) that someone else presents if that person is hostile. This is what is known as having TACT when having an arguement/discussion with someone. You have the ability to change some of their minds simply by being polite and offering research and facts. People who are openly hostile, will never be able to change someone elses mind.
Some people here just want to bash truthers because ti's fun. I'm doing this because I feel that it's necessary to at least try to pull a few of the souls who aren't too deep out of the poisoned well of 9/11 truth. This is being a "good guy". And if we are supposed to be the good guys, we need to act like [rule8]ing boyscouts. Not a bunch of 12 year olds on a playground.
