Then let me be clear the CIA at least and probably other intelligence apparatuses are specifically pushing known obviously nonsense theories to discredit more believable ones. For example Icke, and Flat Earth pretty clearly nonsense, the Pentagon using SF forces to run drugs out of Ft. Bragg to get black ops money lot more believable.

The CIA has no need to fund Icke

There are certainly specific cases where this tactic has been used, but yeah, this is the blanket version. "Blanket" assertions and generalizations (often sentences that start with "the elite") are one of the common red flags that indicate you might be dealing with the classical "nutty conspiracy theory".
