What you've just described is pretty much the foundation of all conspiracy thinking and rationalizing. It also serves to explain why (and simultaneously, at that) there is both no evidence of the great conspiracy and everything can be evidence of the great conspiracy. The conspiracist is so invested in pinning responsibility to who- or whatever they've decided is the source of all of their problems that they will construct these elaborate towers of reasoning to justify their investment.

Anyone who comes along and points out the much simpler and (likely) more accurate explanation is derided as refusing to accept the "truth," typically because they're an agent of or shill for the conspiracist's responsible party. It's almost like a cult, except that you can't actually deprogram or otherwise break them loose from their delusions. Because they treat the very attempt as proof that they're right and that their enemy is trying to silence them.

And it's both hilarious and sad that I'm saying this on Saidit which, almost daily, offers lots of examples of this mindset in action.
