Is the HP vs Twilight stan war really that big? It just seems like a bunch of pressed Harry Potter stans talking about how bad Twilight is + Twilight stans remaining unbothered/unaware of the internet outside of fanfic + twimom forums.
It might not have been on the same scale as Britney v. Christina, but the Cheryl v. Nicole feud got pretty hairy there over the summer with all the X Factor business.
