There is such a thing as “White Magick” which is in direct opposition to “Black Magick”. Example would be, remember the chant the classroom of kids on 9/11 with George W in the back of the class? Pure affirmations for destruction, and then you have this example, with no previous knowledge of that lady and her group I cannot comment but the affirmations they were reciting didn’t seem satanic or dark in nature. Satan wants you in bondage, not to be free, and as for invoking the Arch angels I think that’s pretty common in the white hat side of the mystic world, also remember when a D-list satanist put a “Binding spell” on Donald trump, had some big event in Salem Massachusetts probably around the 2016 or just after, and a lodge of The Order Of Golden Dawn that I was watching on YouTube at the time was super pissed about it, had followed some stuff previously and never saw them get worked up about anything really but this really struck their nerve so they held a similar event to negate it with their magical workings, I believe in California even lol but I know this topic isn’t always well received and most people see all these people in these spheres as LARPers but I’d suggest to do a little research and keep an open mind. So I’m not writing Flynn off just yet
