That doesn't make any sense. You're saying you have made some sort of value judgement, presumably based on logic and information, but if someone sends you a piece of propaganda you'd totally change your position? You don' t play poker, do you?
Sending out propaganda is a new piece of information. When someone is trying really hard to get you to believe something, or act in a particular way, that in and of itself is informative. You don't play Magic The Gathering, do you?
Many humans, when treated with contempt and addressed as if he's a gullible moron by someone who patronisingly tries to lead him into a decision explicitly to that patronising jerk's advantage, often dislikes it to the point of generating what we might call the "fuck you, I won't do what you tell me" response. People who play poker yet somehow aren't familiar with humans will struggle playing against them.
