An argument brought on by disagreeing opinions about Twilight, the young adult novel series authored by Stephanie Meyer. Arguments are not limited to the books, but also include the movies and merchandise. These arguments often occur between Twihards and Twihaters.
Topics of discussion include Edward's alleged abusiveness, Meyer's controversial use of the word "chagrin," comparisons with other Vampire mythos, and alleged Mormon apologetics contained in the series.
