You nailed what motivates conspiracy theorists. Happened to my friends, the ones who are most isolated. They’re so depressed, bored, feeling unimportant, that they have to be part of a cult.
A telltale sign of a conspiracy theorist, the ones that I know, is they talk a lot and they won’t listen. They are there just to convince you of their opinion… they don’t care about yours, they don’t wanna hear it. They’ll fight you on everything you believe without exception, they’ll keep going back to their theories without commenting on anything you say, and they’ll never ask you your opinion .
