You’ll find a lot of arguments for believing such things if you look for them. Some of these arguments are simply angry rants (and they appeal to angry people who aren’t inclined to think analytically) but others are quite sophisticated. Have I refuted all the sophisticated ones I’ve come across? No, that would take a lot of effort, and maybe some of them are even technically true. I’m not convinced by them primarily because I have certain assumptions about the world: conspiracy theories are generally not true, most people just want to live a good life, kindness is usually reciprocated, and so forth. Someone who holds the opposite set of assumptions (every organization is corrupt, many people are inherently evil, kindness leads to being exploited, etc.) won’t be convinced by your “knowledge against it” without even hearing you out in the same way that I’m not convinced by the arguments for it.
