Milner and I explore this difficulty in our chapter about the satanic panics of the 1980s and '90s, as well as its Trump-era reboot. The harder you try to disprove theories about satanists or the Deep State to people already convinced that you’re in on the conspiracy—or are sympathetic to the evil them—the more likely believers are to respond to your debunk with obstinance. Beyond that, they might reframe your “evidence” as proof that they’ve been right all along.
It’s not easy to reason with a conspiracy-theory believer, let alone hordes of them online.
