A conspiracy theorist is someone who believes that something else happened in an event. Such as the conspiracy theory of Princess Diana. Everyone either believes she was killed in a car crash or her own family killed her.
Explanation:
A conspiracy theory is an explanation of an event or situation that invokes a conspiracy by sinister and powerful actors, often political in motivation, when other explanations are more probable. I got this of of wikipedia i didn't know how to explain it.
