What you need to think about is what consequence any of this has to your life. The reality is, like the moon landing, it means absolutely nothing to the decisions you'll be making whether it's real or not. Like holocaust denial, the only reason people make one claim rather than another is to be seen as a certain type of person.
To me honestly it appears that the consequences of such beliefs are relevant. If the WTC went through a controlled demolition, this affects the standard view of what happened next, and should influence your beliefs on politics and terrorism at least. This can be relevant to evaluate what to expect from the future and should influence some future decisions. The moon landing is less relevant, but it still says something on the limit of what humanity can achieve under a strong pressure, and can be a factor if extreme conditions manifest in the future (e.g. a huge impending natural disaster). Finally, the holocaust is one of the strongest arguments against dictatorship and expressions of racism. If it didn't happen, your priors against a dictatorship being a good form of government should be modified.
I hope I'm not breaking any taboos here. It's been a while since I've come onto the discussion section and I admit I'm not too up to date on the topics.
I'm having difficulty responding to someone who is convinced that 7WTC was brought down by controlled demolition on September 11th, 2001. They're referencing the controlled-looking destruction of 7WTC and various other incriminating looking things. Thermite and thermite waste products seem to come up a lot.
Now, I have definitely noticed I'm confused here. While I hold the opinion that the towers went down because of the planes/fires (i.e. the standard explanation) I have difficulty seeing how the falsity of controlled demolition is the slam-dunk folks seem to think it is. Could somebody walk me through this?
