"Idea Diversity" Can and Should Exclude What's Been Disproven

 There is a complaint often heard that says something like "intolerance of idea diversity" is too pervasive and undercuts the claims that people are actually searching for the truth. This idea that gets expressed in many ways is not accurate, however, unless it includes the caveat that old and disproven ideas don't need to be tolerated. It is perfectly fine--and a necessary component to the advancement of knowledge--to leave behind those things which have been superseded with new information. I find that a large number of the people who get on this "intolerance" bandwagon refuse to accept that their idea(s) has been shown to be wrong. The misdirected claim that they are somehow being unfairly discriminated against is a desperate effort to stay in the game with faulty and irrelevant claims that mask some other agenda.
