I was not really sure whether there actually was a word like "conspirationist", but when MS Word highlighted the word in red, I knew that my hunch was right. There is no such word as that.
But even if there isn't a word like that, it is the word which best captures the state of mind which is common to most Indians , including me : belief in the theory of conspiracy !
We always strive to find the conspiracy behind every statement, every act, every gesture, and every something !
