Although conspiracy theories are nonsense, and dangerous nonsense at that, it's often impossible to show that they're demonstrable nonsense.

Conspiracy theorists and their ilk are savvy when it comes to articulating their notions in a way that makes it impossible to refute. No-one can demonstrate that Bill Gates has not contaminated the vaccines with microchips, even though the notion is just stupid nonsense. I hear that some believe that there's a supernatural, all-knowing, all-seeing, all powerful being who has no beginning and no end. It's the most ridiculous idea I've ever heard, but I'm still unable to demonstrate that is isn't true...
