First of all, you don't have to believe everyone's opinions, but at least entertain the idea with an open mind.
I'll start with mine. I've been following conspiracies somewhat since the loose change movie about 911 when I was a kid but I was generally asleep to most other things. Mine happened last summer when I'd open Facebook or Instagram and everywhere I looked I'd be bombarded with some girl named Greta Thunberg, everyone praising her like some prophet of God or something. It got so bad that I finally asked myself why is every media station cramming this down my throat? Why do they want me swallow this up so bad? So that's where I started researching, I found a website called realclimatescience and started reading his research and articles. It was actually real scientific research and mentions facts that no other media has told me. I won't get too specific on all this but after a lot of research I came to the conclusion that I've been lied to about the climate crisis. Massively. By so many different institutions and media companies, it's mind boggling to comprehend that so many people are either in on the lie, or have also been duped by it. This started another awakening. From then on, I learned that when the mainstream media are all forcing the same narrative all over, you should always question it, and basically, lean in the opposite direction. Next thing I know, covid happens, then George Floyd, then the election. Once you catch on and wake up to the lies, they're easy to spot.
For whoever read the whole thing, I'd be happy to go deeper into anything I mentioned that you disagree with. Otherwise, what's the story of you waking up to the lies?
Let's be real, everyone's first "conspiracy" is Santa Claus.
