“The bigotry of theologians [is] a malady which seems almost incurable.”
― Scottish philosopher, historian, economist and essayist David Hume (1711-1776)
We may also ask the questions following David Hume's lead on the matter of theologians' incurable disease of bigotry: Why do many theologians and preachers behave in this way? What lies at the roots of this disease that makes these people to think in such inhuman terms to the detriment of other people and the followers of seemingly different beliefs?
There must be some potential causes, and unless we deal with those causes that create the disease of bigotry and hatred against other human beings with different religious or social orientations, the morbid affliction of bigotry and hatred will not disappear.
