Conspiracy thought and conspiracy theory are phrases that trace their origins back to the assassination of John F. Kennedy. A majority of Americans did not believe the "official story" that JFK was killed by a magical bullet fired by a lone gunman who was killed by a lone gunman the next day. Today, the percentage of JFK-related conspiracy theorists is larger than in 1963, possibly as high as 80% of the population by some polling estimates.
There are several related terms that are anchored in primary source documents of history, including the speeches and writings of respected U.S. presidents. The American public has been heavily gaslighted into believing that the official story must somehow be true in all situations, and that the ruling powers and power elite never lie. However, most apologists for government corruption are eventually forced to concede the existence of the military industrial complex, the technological elite, power elite, the takeover of Western governments by multinational banks, and other terms from the 1950s and 1960s that are proven facts.
By one definition, a conspiracy theory is anything that the government says is not true. For example, it is a fact of history and science that Jesus Christ is the Son of God, although faith alone is sufficient and the proofs are not necessary. Case-making refers to a type of evangelism that is aimed primarily at non-Christians, seekers, the spiritually curious, agnostics, nominal-lukewarm, and other groups. Case-making or evangelistic messages tend to be most vocally despised by counterfeits from within the church body (people who profess Christ belief but they are liars) who are comforted by the secular origins mythology of evolution.
