Furthermore I and many other people who think it was a US government involved conspiracy also believe the conspiracy involved crashing planes into shit

I think this is the key takeaway here. The actual mechanism of "DID THEY FAKE 9/11!??!?" doesn't matter anywhere near as much as what it was used to accomplish. Like oh no add another 3k to the 5M dead in Iraq, it's a drop in the bucket. The US government kills its own citizens all the time.
