Query: People shouldn't dis her.

The whole "Avril is a poser" thing is really old. You don't know her personally so you shouldn't be able to judge her. If you don't like her music, then don't listen to it. It's as simple as that. You weren't asked to tell about how you feel about how she dresses and what not, you were asked to review the CD. To the people that like Avril, her songs make them happy, and that's all that counts.
