Bill Maher was a huge disappointment on Friday night's Real Time. He told the 9/11 Truthers that they need professional help. To take time in your show to bash your viewers isn't too bright. There is a lot more to questioning that day than whether or not the buildings were controlled demolitions or whether or not a plane hit the pentagon. Even if you buy the government's theory on those aspects, there are still huge amounts of unanswered questions.
Not all 9/11 Truthers are on the same page about what they think really happened that day, but calling for more investigation doesn't make one crazy. Many arguments on both sides are quite compelling. I'm not a physicist so I leave those arguments to experts. But in fact, NOT wanting to get to the bottom of what really happened on 9/11, Not willing to ask tough questions and hoping that those who want answers will just go away is crazy. We just talked about that here at the blog. Closing your mind is not progressive.
