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?
Years back I found it interesting that people truly thought, in some occasions, the complete opposite of popular opinion on spectacular events like the moon landing or the September 11th attacks on New York in 2001. More interesting than I actually believed it myself.
I believe though, that under pressure and watchful eyes, people don't always have the mind-power to stop themselves from accidentally saying what they really mean to say about certain things. That's why when I saw a multiple videos of breifings/meetings where people slipped up saying that "we'll finally be able to leave low Earth orbit" or "when United 93 was shot down", I really started to pay more attention.
I wouldn't really consider myself a full-blown conspiracy theorist at this point, because I think that term is, right now, synonymous with "idiot" (sadly). I more just like to see as many sides of any issue as I can and try to form my own opinions on what seems most reasonable and likely based off of the subjects past.
