It's only amorphous because the very label of "conspiracy theory" is amorphous. Much like the istaphobe labels, it lumps together so many wildly divergent ideas and then provides opportunities for gotchas based on conflating different groups of people.

Sure, you can poke holes in any "conspiracy theory," but you're assuming from the get-go that holes in the official account necessarily have mundane explanation. This accusation of unfalsifiability goes both ways.

As for the thermite point, what makes me raise an eyebrow is that there was never a proper forensic investigation of the rubble made in the first place, the vast majority of it was immediately shipped off to China to be melted down. So that's already very suspicious, you'd think that our government would be very interested in thoroughly investigating what happens when an airplane crash allegedly causes structural failure in a skyscraper. That kind of knowledge would be very useful for national security purposes, after all.

Moreover, there's glowing yellow-orange liquefied metal pouring out the side of the towers. And aluminum melts prior to glowing orange, and immediately turns back to its silver-grey color once it's removed from the source of heat. Yet the molten metal pouring out of the towers retained its orange glow all the way down, and in contrast to aluminum, iron and steel glow orange prior to melting.

That, btw, is what the "kerosene doesn't melt steel memes" point was about. Everyone knows that kerosene can burn hot enough to soften steel, but deboonkers always ackshually this meme to evade the point being made.

To be sure, maybe there was something else that melted from the kerosene, I'm open to being proven wrong, but I'm not sure if you can say the same.
