Some conspiratorialists do indeed overdraw the picture by expanding the conspiracy (from the small clique which it is) to include every local kneejerk liberal activist and government bureaucrat. Or, because of racial or religious bigotry, they will take small fragments of legitimate evidence and expand them into a conclusion that will support their particular prejudice, i.e., the conspiracy is totally "Jewish," "Catholic," or "Masonic". These people do not help to expose the conspiracy, but, sadly play into the hands of those who want the public to believe that all conspiratorialists are screwballs.
