Before COVID, I had some interest in conspiracy theories, would often watch YouTube videos from popular content creators where they would talk about some of the biggest theories like 9/11, Mandela Effect, Simulation Theory etc. but also discuss smaller ones related to individual celebrities like if Paul McCartney died years ago, for example.
It was always just a bit of fun, something you would watch for a laugh but also sometimes it would make you think... and then I'd send it to my partner or a mate with a similar interest of watching these and you'd either find a way to dissect the theory or you'd stop and think... hang on!
I have to point out though that these were pretty much always videos made by verified content creators/YouTubers who would just make the videos because they had a similar interest and because they would always bring in the views, like millions.
Although I had this mild interest in conspiracy theories, I never thought COVID might have been one of them, ever. In fact for me it was the time where I had a bit of an awakening (or anti-awakening in this case?) where I had to stop reading certain stuff, such as Reddit, and had to tell people to stop sending me COVID theories as it was getting too much for me, would leave a sour taste if I came across something and just generally wasn't happy.
Then sometime during the first lockdown, there was a 'theory' about the company Wayfair supposedly using their products and website to disguise their involvement in child trafficking, and I would hear family members who would normally dismiss such a thing that began to believe these type of thing. The vaccines were being kept back until Trump wins the election was one of them. I think that was the last straw for me.
It's almost like a cult these days, one big group of sheep, despite what they call 'non-believers', who go from theory to theory, latching on to the current biggest story in the news. Matt Le Tissier is a perfect example of going from a COVID expert to a war propaganda expert.
