Can say this much, I flirted with 9/11 Truth, mostly from being a longtime reader in JFK assassination theories (I was a weird kid and saw Stone's "JFK" in second grade, what can I say). After starting in 911 Dispatch and seeing how wrong eyewitnesses can be on what they see or hear (for example, you can have a vehicle accident that 10 people see and get 10 different descriptions of what cars were involved, along with exaggerations, etc) I did an immersive period of checking sources cited and comparing the record with what was quoted. You'd find discrediting testimony hidden away in ellipses, like JFK witness Jean Hill, who is always touted as seeing a man firing a gun on the Knoll, but rarely will a CT ever tell you she said she saw a dog between Jack and Jackie. After doing a lot of reading, to the point I never want to read anything else about Dallas '63 ever again, I shrugged off conspiracism and am a lot better about approaching things based on evidence, and if I speculate, it will be based on what I can prove and where it leads.

My point is this: there will be people who can see their way out, but it will require willingness on the part of the person who undergoes conversion to see beyond their construct. A good majority of people in QAnon and the far right do not have that at all.

My best suggestion is to be supportive to someone who shows potential for change. An unfortunate reality I have learned in dispatch is that not everyone can be saved. Its not a great feeling losing someone with CPR, and its not a great feeling seeing a mass movement sweep people up either.

Just take care of your mental health in this. Be there for those you recognize can be helped, but do not follow them down either.

If you're already on the side of reason, that's enough of a contribution to a world that sorely lacks it as of late.
