What claims does Bissinger make about fandom in chapter 2?

This chapter details the "Watermelon Feed," the season's first pep rally.

For this event, the boys run into the high school cafeteria with all their glory on display. It is difficult to pack the bulk of white Odessa into a school cafeteria, so the school positions screens outside for latecomers. People arrive with their children, as though the event is an important civic duty, all clutching Permian yearbooks and autographs from players now graduated.

The town makes no apologies for its behavior, even though grown men act like crazed fans at a rock concert. When Ross Perot, while running for office, once called these men ‘football crazy’, the men reacted by sending letters insulting the politician.
