Creative Speculation

You say here that you're "just seeking information." But I think most people who read the OP would conclude that you've already made up your mind. Honestly, wouldn't you? I mean, you wrote that you "only consider information from Engineers or Physicists," but the Journal of 9/11 Studies isn't exactly an engineering journal. I'm not saying you have to ignore it, but can you see how this looks to other people? (Suppose someone linked to an article in the Creation Science Quarterly -- assuming there is such a thing -- and said that s/he only considers information from biologists: how would you react?)

Now, just from reading that post, I can't tell whether you're actually interested in learning about this topic or whether you've already decided. From other posts, I'm inclined to give you the benefit of the doubt. There's nothing wrong with reading one side of the story and not seeing the problems with that side. However, it's fairly common for people to post threads in which they try to pose as open-minded, but sooner or later reveal that they aren't. So, if people seem to be jumping to invidious conclusions about you, it's because (1) the OP doesn't seem very open-minded and (2) many have poisoned the well before you.

I don't think anyone here expects "the government" to tell us "the whole truth" about anything in particular. That really isn't the issue here.
