...in the Battle for September 11th Conspiracies.
I think your victory is a bit premature. While I know what you mean in your statement. I think you might be fighting the wrong battle. While it is true that each of the posters you mentioned are unable to prove their case, their ability or inability to prove their case in its own right has a greater depth to it.
The attacks on September 11th, 2001 were committed by agents of Al Qaeda. Victory is achieved simply by realizing this. The problem we have as skeptics is that these people we are debating against do not understand the scientific method or even simple logic for that matter. They fail to realize when their beliefs have been disproven because they're unable to grasp the reasoning behind your statements.
So, when you disprove their argument, you do not achieve victory, you simply prove their ignorance. While this is still a victory of sorts, people sitting on the fence surely see your efforts and hopefully see the errors in logic that the Truth movment hold so dear, it does nothing to change the mind of the person you are debating. The only way to claim victory is to combat their ignorance and the only way to achieve that is through education.
Unfortunately, an internet forum isn't the best place to educate an unwilling student, especially when the student is as insulting as many you mentioned have been. Of course this becomes even more difficult with other people posting that are more interested in berating than educating, something I've been guilty of on occation...
However, when it really comes down to it, you have to ask yourself if it's worth the effort. Why educate someone who is unwilling to educate themself? Personally, I believe it can be worth the effort, depending on the "student."
A prime example of this would be RandFan, who is a greatly respected member on this forum, well by myself at least. However, when he first joined the website, he was a proponent of Intelligent Design. I won't go into great detail, since he already has
here and
here. RandFan's conversion demonstrates the power this forum has and what we can accomplish if we try. Not only were we able to help RandFan make some discoveries about himself and his beliefs, we were able to add a greatly valued member to the JREF team.
Realistically speaking, I'm certain that the majority of the people you listed in your OP are likely beyond hope. They're simply too driven by their beliefs to be able to consider another point of view. However, we do have other CT believers for which there is hope. With time, perhaps they'll simply prove no better than their bretheren, perhaps they'll show themselves to be another RandFan, who can say?
I want to make clear, I'm not posting this to call on everyone to work together, make nicey-nice and help these people to understand. I realize that none of us has made a commitment to become educators of the ignorant. Also, I certainly do not want to point fingers, make judgements, or berate anyone. However, I wanted to provide some perspective to hopefully show that the victory you speak of is simply too hollow to be worth the effort. That being said, perhaps we can work together to achieve more.
IMHO, as always.
