Now that you bring up the subject of changing the article name Im inclined to think this might be the best approach It might enable you to retain the bulk of the existing content  which Im sure would be your primary aim  whilst removing the main concerns that I and others have expressed about the page   If we take the alternative approach  of giving a correct definition to the term at the outset  then I think that is inevitably going to mean major changes to the content to conform to the new definition And that is obviously going to be a lot more problematic IMO
