Is it possible that you are the one that has been manipulated by misinformation? Is it possible that people can disagree with you without "misinformation" being involved?

Oh, there is no doubt in my mind that I’m susceptible to propaganda, including misinformation campaigns.

However misinformation campaigns are a fact of social media. There are several documented cases of misinformation spreading. It is possible that I have just been lied to about that the media et.all lied about the scale and severity of misinformation and I believed it (although, wouldn’t that be a misinformation campaign which proofs their existence?)
