Isn't it wild? I just joined one out of curiosity via a Reddit post, and since then I've fallen down all their rabbit holes. There's thousands in their groups and they're all equally bonkers. Never seen anything like it!
It's pretty sad. My mom fell into it hard around 2018, and back in 2020 when I stopped talking to her she was going on about how some guy in Montana was now the official ruler of the US because he filed an application to claim the United States flag during some obligatory grace period before the US sold it to the King of England. Mind you, this was before the queen died - she was convinced that the previous king was still alive and scheming to regain British ownership of the US, and that this Montana guy saved it at the last second. She was literally crying in joy.
Not sure if it was actually a SovCit conspiracy, or if it was Q or something else. Once she was down the rabbit hole she spent literally all day on YouTube just watching conspiracy videos.
