Pointless sophistry? To which your counterargument is "moving on..."?

Yes, of course you have to identify the "experts" in order to know what their perspective is. In this case, the vast majority of knowledgeable people have settled around the consensus that the "official" explanation (two planes crashed into the WTC) is indeed plausible.

But you ignored my second point entirely: if there is (reasonable) dissent, then you can't just pick one side and say they're correct. In fact, by not knowing the underlying science, you can't even participate in the debate. So there's no point in saying "a bunch of engineers and architects have signed their names to this paper saying it's all a conspiracy" when you have no idea why that's the truth (if it were).

Finally, spreading uncertainty and doubt (what about what I said is spreading fear?) is a good thing where false certainty and false wisdom prevail.

"Yes, of course you have to identify the "experts" in order to know what their perspective is. In this case, the vast majority of knowledgeable people have settled around the consensus that the "official" explanation (two planes crashed into the WTC) is indeed plausible."

See? That's sophistry. Instead of explaining (or rather, thinking about) how one would identify knowledgeable people, you skip to what they are allegedly saying. Also, citation needed.

"In fact, by not knowing the underlying science, you can't even participate in the debate."

But here's the thing, I do, and I do have eyes. So I'm all up for the debate, but it's mostly hand-waving like you just did. 9/11 was stonewalled and swept under the rug. I payed attention back then and nothing new came up since then, you didn't post anything either.

"what about what I said is spreading fear?"

You cannot possibly know everything, better ask the experts. (Who are the experts? Ask the expert experts?)

I am not a qualified (knowledgeable in relevant disciplines, formally tested, fairly competent) engineer. I can:

1. Defer to the majority opinion of qualified engineers, if one exists.

2. Hold no opinion whatsoever.

3. Become a qualified engineer.

I am currently doing (1) because I believe a majority opinion exists and that opinion is "airplanes hit the WTC on 9/11". If that is not true, then I would accept evidence to the contrary (high statistical confidence, random sample, repeated by multiple sources).

I could do (2), which would be perfectly legitimate, but I do not feel it is necessary (I am not aware of any dispute among even a sizable minority--I define sizable here to be at least a third who either disagree or are uncertain).

In order for me to do (3), I would need to take a few years off work and study engineering full time. Even then, I may not have what it takes to become a qualified engineer. Unless you are willing to pay for this option, you can't fault me for it. I am not pretending to be an engineer.

We live in a world of finite possibilities. I am no more demanding that you should understand advanced mathematics (what I know most about) than you should demand I understand civil engineering and materials science. I would expect you to accept a consensus of mathematicians on such matters, just as I've accepted (what I believe to be) the consensus of engineers.

That's what I like to call living in the realities of an imperfect world.
