Why is Rosalie so unpopular in the Twilight fandom?

She seems anything but a Mary Sue, and believe me when I say that. She's vain, shallow, and kind of hostile towards Bella at first. She's not perfect. She's no disney princess who sings to chipmunks and has little animal friends who cater to her every whim. She has a temper that puts a lion with a bad case of PMS to shame on that count.

Remember that the way she acted to Bella was only because she felt threatened. She thought Bella was going to reveal their secret. That just shows that she cares about the safety of her family, right?

Can tu imagine being shown up por someone clearly inferior to you? That might sting.

Rosalie really isn't that bad. Just that after lectura a few hundred pages of limited insight about Rosalie, when all of a sudden she goes all soft, the damage done might not be reversible.

So please hear me when I say that Rosalie isn't such a horrible character. She really isn't.
