Note that if you're using the term "conspiracy" in the strict sense, it's not contrary to the official narrative. The official narrative for 9/11 for instance, the 9/11 Commission Report, is terrorists conspired to crash airplanes. In the colloquial wishy-washy sense, that report is not a conspiracy theory, despite being a theory about a conspiracy. However every other theory that disagrees with it is a conspiracy theory.
