A conspiracy is simply 2 or more people telling a lie. So if you and me make up a lie then we are engaging in a conspiracy. The term conspiracy theory attempts to discredit honest people by claiming that 2 or more people never lie as a team. I know that's not true, so do you.
Your premise is incorrect due to the incorrect definition of conspiracy. Are we now deciding the meaning independent of Webster? Conspire implies illegal or criminal intent by a group. Not as you assert ..."a lie". I think you have a thirst to argue, not a thirst to learn,
Can you not just look up Google?
~ a theory that explains an event or set of circumstances as the result of a secret plot by usually powerful conspirators
~ a theory asserting that a secret of great importance is being kept from the public
~ an attempt to explain harmful or tragic events as the result of the actions of a small powerful group. Such explanations reject the accepted narrative surrounding those events
~ is an explanation for an event or situation that invokes a conspiracy by sinister and powerful groups, often political in motivation, when other explanations are more probable. (the term has a negative connotation, implying that the appeal to a conspiracy is based on prejudice or insufficient evidence).
I believe the term is conspiracy theory theory, meaning the use of the term by power to discredit anyone who challenges the official narrative of power. The term is so loaded now that no one is their right mind ever wants to be called a conspiracy theorist. Mission accomplished by power. The term will invoke the same negative response from this site. I can see that you were trying to define the expression in its literal meaning. Collusion and conspiracy are well known activities associated with criminality and corruption. Anyone remotely connected to the real world knows that wealth and power do this all the time. Form a theory that this has happened in a specific case and bingo, you are a conspiracy theorist, in other words a crank. Case in point: Interesting, isn't it, that loads of people think Jeffrey Epstein was murdered. Even on mainstream US TV this is referred to. Yet, no one who thinks this would admit that they are conspiracy theorists, although they suspect that power conspired to have him murdered. What I dislike is the lack of distinction between serious questioning of official stories and narratives by power, and waco theories about aliens in Atlantis secretly running the world. Now it's all lumped under the term conspiracy theory. I despise this.
You say, "The term conspiracy theory attempts to discredit honest people by claiming that 2 or more people never lie as a team."
Trying to understand: if I am an observer, and I claim "conspiracy theory " about 2 people "over there somewhere", are you saying I am calling them liars because I say they are conspiring? Or. Are you saying I would be the liar for claiming conspiracy theory about those 2 people over there?
