Conspiracy theories thrive in environments of silence. If no one can talk about their time in government organizations (military, CIA, etc.), speculation is all we have left.
in my experience; speculation fuels distrust, which fuels more speculation, which leads to a spiral.
similar thing as gossip. why would i trust you when you’ve been gossiping with me about our mutual friend? then i go off and gossip about you gossiping to my other friend etc.
loose lips sink ships — the things we say have consequences.
there's enough bullshit for people to deal with in the world. why add to it?
