I’m pretty sure that anyone who is willing to swallow massively implausible theories like qanon is not the kind of person who will be amenable to logical arguments and fact checking. You can’t just argue those people out if their positions because it’s not about truth for them, it’s about feeling like one is a member of the elect. Denying reality is not a bug, it’s a feature of every millenarian belief system. Facts are ineffective, you just have to shut them down.
