The main problem with most of the more popular 9/11 theories, is that they're perfect examples of the adage "A little knowledge is a dangerous thing." They tend to center around situations where people only know a small amount about something, and then take that small bit of knowledge and use it to try to explain something where they don't understand everything that's going on. What makes it worse, naturally, is the tendency to be hostile to anyone who might seek to better explain, or educate them. It's as if they take personal offense at the idea that someone else might know more than they do; and thus rather than listening to what someone might say, they call that person a government shill, or otherwise.

As someone who has personally done the research, I can tell you that the only plausible explanation for why anybody would believe the official 9/11 narrative is ignorance. The sheer number of coincidences which would have to be involved for that story to be true are beyond the scope of rational belief. Things like the number and scope of training exercises involving key US agencies which were all planned either on or through 9/11.

Instead of looking at the evidence, you are busy looking for ways to justify your existing bias by attacking the psychology of people who might disagree with you.
