I agree that the Twilight hatedom is starting to sound ridiculous. However, I can sympathize, assuming most of the hatedom consists of middle schoolers. As someone who was in midde school once, I can't blame them. As you get older, if you don't like something, you can ignore it. In middle school however, you are stuck in the cesspit of bad taste that you can't escape unless you were to try dropping out of school.
As an adult, I see Twilight posters ever now and then, and find Twilight books as I walk through the book stores. Middle schoolers, however are stuck dealing with the fangirls every single day. Bottom line: If you're a middle schooler and need to vent, be my guest. Everyone else, find something better to do.
