I’m sure much of what a conspiracy theorist says is just that. Conspiracy. Falsehoods. Misunderstanding and Lies.
But how do we really know? We think one thing and many years on learn that we were hoodwinked. MKUltra for example.
There are indeed government secrets, classified information and much we don’t or can’t know about the world we are living in. We are gaslit and fed information to better control the population and there is such a thing as behaviour change, which is a method used to enforce or encourage societal behaviour change, as well as social engineering. So maybe your husband is right and you are wrong. Who knows.
Another thing is that for many people, Covid and the way it was dealt with broke trust in authority. That opened the door to conspiracy theories gaining traction, spurred on by social media.
All I can say is that I like to think events like 911 were awful terrorist attacks and nothing closer to home. I like to believe we are told the truth about things that are important. But if I find out in 50 years that some conspiracy theories held merit, well, I doubt I’d be that surprised.
And without irrefutable proof one way or another, I find it hard to hold someone else with alternative views in such contempt as you do op. I personally would simply not engage or feign mild interest and ignore. But to consider divorce suggests a level of intolerance, that is quite typical of the left leaning these days.
