It's a bit shocking to me when I see people online putting 9/11 conspiracies in the same box as "MAGA" conspiracies (for lack of a better term, sorry).
For reference, I was 24 in 2001 living in central NJ. Even without social media or fake news websites or what cable news has become today, I have vivid memories of people having the firm belief that there was something up with the attack on 9/11. Was this just my social circle?
Jet fuel melting steel beams was one of the more fringe and unfounded (and quickly debunked) ideas but the rest of everything on that day was questionable. Tower seven falling, the missing plane debris at the pentagon and central PA, the military / president not responding to known threats, if a person with limited flight time could hit a tower, the fact that Bush attacked a country that had nothing to do with the event, and so much more are still, I thought, reasonable questions - especially when looked at together.
This is not about rehashing each theory. Or maybe it is? Have I missed that everything has been debunked?
I mean, I still believe 9/11 was an inside job or at least high level officials, including Bush, were aware it was going to happen and did nothing to stop it. I thought this was still a common opinion of most or many Americans over the age of forty.
For the first few weeks, everybody wanted answers, and when people don't get answers, we make them up.
I remember hearing and seriously considering nearly all of the theories you mentioned, but as we started to get more answers, most people just forgot about, or stopped listening to the conspiracies.
Unless, of course, you were DEDICATED to one of the conspiracies, and surrounded yourself with like minded people who dismissed any evidence that went against their beliefs. Much like MAGA when you mention all the evidence that Trump lost the last election, or committed over 34 felonies.
This is what I think happened. People just stopped caring and defaulted back to "trusting the government" or were distracted by other things like the war in Afghanistan and the 2008 financial crisis.
In my mind, these theories were still prevalent for at least a few years after the attacks. And now, 20 years later, people forgot so much that they've accepted that only weirdo internet trolls believe in these fringe theories.
In hindsight, there were signs that could have prevented or lessened the damage of 9-11, had we taken them seriously, but you never know which leads need to be seriously investigated, and which are baseless.
Bush didn't do 9-11. In an alternate timeline, it could have been prevented, but the systemic failures that allowed it to happen were more than we can put on any person or dept.
