I just have to ask, why is Twilight being referred to in the same light as Emo and Goth culture? The only relation I really see is the fad aspect of all 3. Although Goth style has been around for over a decade now, and I don't know that you can call it a fad.
I have read the Twilight series multiple times. Those, and Harry Potter are my favorite books to read PERIOD. I am a complete book worm, and these books are just so much fun. I'm about to turn 30, so I am not the typical audience these books are aimed at. I'm also a mother, engaged, and have settled down in life, so to speak. I have many friends my age, and many older than myself, who ALSO love these books.
If the relation is being made because of the vampires, I must say that these are "vegetarian vampires" who feed from animals so as not to hurt/kill humans. There are actually quite a few virtues the author maintains through the story, such as no premarital sex, no drug use, etc.
I understand that many people don't understand the mass popularity of Twilight, and that's fine. We are all entitled to our opinion. I am just a bit confused about why Twilight is being related to Goth or Emo cultures, other than that many of the fans may ALSO subscribe to said styles. In actuality there is more death, and horror in Harry Potter than in Twilight.
