1/4 If you know someone in QAnon-the next few days/weeks are a time to reach out. Getting out of conspiracies is best done by people loved & trusted, and a moment the lie is punctured (i.e. Biden now Prez) is a moment of openness. I'm not the expert here, quoting some who are:
1: Don't debate on twitter and facebook. And don't shame or mock misbelief. This is a heart-rending and identity-devastating moment to people who believed. "Don't confront me with my failures/I have not forgotten them"- Nico. They need love and outreach: https://www.nytimes.com/2020/10/25/opinion/qanon-conspiracy-theories-family.html
2: Don't argue facts, instead encourage doubts - QAnon actually encourages people to interpret for themselves, and you need to help people who actually already have internal doubts admit them, rather than defensively defend against them: https://www.theguardian.com/commentisfree/2020/sep/28/if-your-friends-or-family-have-fallen-for-an-internet-conspiracy-cult-heres-what-you-should-do
3. Join some of the online groups of others who have helped family and friends get out, read former members describe their journey out, and learn together: https://www.rollingstone.com/culture/culture-features/ex-qanon-followers-cult-conspiracy-theory-pizzagate-1064076/
