Basically what Tannen is stating in the section about the sports, is that sports commentators are from the devil. It is hard to tell why she put this section in the book. In this case, Tannen, failed to do so. When an avid sports watcher reads this section they are going to disagree with her because they love sports and believe that fighting is an intricate part of them. No one wants to see a low-key announcer.
People watch sports because they are filled with action and battles.
Take either of those out, and ratings will most certainly drop. Most sports fans are going to disagree with her, and that is why this argument is a poor one. The authors arguments must appeal to the reader. To illustrate my above point I ve chosen the sports commentary section, where Tannen shares some research that three men have gathered. Their research told of how viewers were shown two different segments of a hockey game without the commentary.
