Conspiracies can (and do) happen all the time. The Iran Contra was an infamous example where people were caught in a conspiracy. Thats just one example, I could list dozens but it doesnt matter really. If people are gullible enough to believe that there is no such thing as a liar in this world, no amount of evidence will reverse their flawed judgment. However, theres always two kinds of people, rational conspiracy theorists, with theories soundly based in reality, and irrational conspiracy theorists, who think lizard people are the REAL culprits here.
Anytime people immediately write something off as a conspiracy theory, what theyre really saying is, "I hope it isnt true." (Or, "I hope I dont get caught so let me try to dismiss this before anyone takes it seriously"). Are there powerful pedos in the world? Sure. Epstein was one of them. He made a living bribing other powerful pedophiles. Of course theyre there otherwise Epstein would have been another guy pushing carts in the Lowes parking lot back to the building. Its how he made and maintained his fortune.
As far as QAnon goes, I think its ridiculous and has no merit. Just people wanting desperately to believe they are the masterminds behind the solution. Just as cultish as the Mask Police. Any degree of anonymity is prone to infiltration, misdirection, misinformation etc. The first time I heard about the Q thing I just laughed. Sorry, this isnt a Scooby Doo episode where everyone is a detective. Ppl have an internet connection and think they have access to the same info the intelligence services have access to (not that they utilize it but still). Its hocus pocus and just another diversion tactic as far as Im concerned.
