There are many different mutually contradictory but often simultaneously believed 9/11 conspiracy theories. In general, though, they attribute the destruction of the WTC to demolition charges planted inside the buildings. Some of these crazy people believe that planes were flown into the buildings (they differ on whether these were the actual commercial aircraft lost that day or not), some believe that these were just holograms, some believe that it was military planes firing missiles at the towers before crashing in to them (I swear I'm not making this up), but in any case I believe the planes/holograms/drones/missiles these idiots believe in were allegedly just a distraction and not the real reason the towers fell.

Well, the fire weakened the supports just like it did in the twin towers, so it isn't surprising it fell in the same way.

Also, my students (who were not alive in 2001) tell me the planes were CGI'd into the picture and the television was on a 7 second delay. Then I tell them my cousin and her husband were in the street and watched the second plane hit. So. Yeah.

Also, I got 20/20. I know way too many conspiracy theories.

The towers didn't collapse because they were hit by airplanes (they took time to collapse) They collapsed because of the damaged the crashes caused to the integrity of the buildings. WTC 7 collapsed because of being hit by the debris from the Twin Towers collapsing. Steel loses structural integrity well before its melting point and is especially problematic in tall buildings.

I've never heard of anyone arguing that "climate change" is a hoax, since part of the definition of climate is that it changes. The alleged hoax is man-made global warming, which has been switched to "climate change" to distract from the fact that global temperatures didn't increase dramatically, as predicted by global warming "experts" like Al Gore who said NYC would be fully underwater by 2016.

Nope on both. The CIA never tried to kill Castro with a exploding cigar. They tried to kill him lots of other ways but the conspiracy about the exploding cigar is unproven. They did not introduce crack into the black community. They funded Contra b/c they were trying to overthrow the revolutionaries in Central America. Internal memos showed that some in the CIA were aware of the drug smuggling but there is little evidence they directly dealt crack (or paid people directly too) and they certainly did not introduce crack.

Nope. All still a conspiracy. They funded the people who helped spread it (Contra) but not because they were trying to spread crack/coke. It's because Contra were fighting the revolutionaries in Central America. The conspiracy is they intentionally spread it throughout the black community and there is no evidence to back this up.

I always keep an open mind for this stuff. Sometimes governments confess the very things they used to deny and the previous 'nutjobs' are proven right. Look at the state of the topic of UFOs, Pentagon itself is talking about them and by looking at the various documents they revealed to the public one can easily tell they deliberately tried to deny and debunk the people who tried to tell their experiences/thoughts. It is clear that official declarations do not automatically mean true, so they are not 100% trustable. That is not to say that we should believe claims without evidence of course, hence the keeping an open mind thing.

"One of these conspiracy theories is actually true - but I won't say which one!"

It's important here to distinguish between rumours and conspiracy theories. The modern usage of the phrase "conspiracy theory" basically means 'something which I and other intelligent people can see is crazy but other people believe to be true'. Hence something will be dismissed as "that's conspiracy theory".

A conspiracy theory may be true or untrue, it is no more likely to be true or untrue just because there was a conspiracy.

Finally I think this common understanding is quite dangerous. If someone actually were wanting to commit a conspiracy then it becomes almost impossible to allege it without looking like a lunatic - perfect for any real conspirator.

Its funny how many of these 'theories' are facts and mounds of evidence support them while other wild theories are thrown in. In other words, Elvis probably died in 77 but the global warming official stance is a conspiracy in and of itself. The moon landing and 911 official stories are certainly bunk.

This way, theories with little evidence are bulked in with theories which are likely true and supported by much evidence. This is an association lumping to discredit likely theories.

It's like saying 'Christians, conservatives and terrorists,' like they all three go together.

The worst 9/11 conspiracy theory I ever heard was by a roommate many years got that there was no one in the Towers when they collapsed.

Having grown up in NJ, I knew a handful of people who made it out safely, and one who didn't. I really wanted to pop him in the face for spreading such a stupid conspiracy theory, but thankfully remembered he was my friend and used that leverage to debunk it.

He now no longer believes that.

It’s beyond fishy mate. Reported by the BBC as collapsed before it actually did fall, in an identical manner to the other two buildings, which had superheated jet fuel penetrate the core building supports. Apparently. And 7 tumbles like a replay. Nothing to see here. I don’t suppose there was a spare plane that might have failed to hit its intended target anywhere? Can’t leave all that thermite lying around eh…

Feb 20, 2025
The BBC just made a mistake in reporting—shocking, I know.

WTC 7 received catastrophic damage from the collapse of WTC 1; that, coupled with the fires it started, made the building so obviously unsafe that firefighters deemed it a lost cause and pulled out efforts to put the fires out (hence the infamous Larry Silverstein "pull it" quote which I never understood as conspiracy fodder as why would he admit to demolishing them in a TV interview).

Note how almost all the footage of WTC 7 you see from that day showed its undamaged north face; meanwhile, the other side had a long hole cut from nearly top to bottom, with smoke pouring out. The Deutsche Bank Building suffered a similar but much smaller hole from the collapse of WTC 2.

the CIA from their own internal memos did try to assassinate castro with an exploding cigar. see operation mongoose

bill gates has expressed interest in putting nano-chips in vaccines, whether he has actually accomplished it is another matter.

i doubted the CIA crack thing, but as i've read more over the years, it actually is beginning to seem less far fetched
