Hm, well, your reading is your reading certainly. I haven't read the book, but I don't think someone is saying that Twilight is without its deep problems, she was just speculating about the reason of its uber popularity.

Something that it's very pervasive in media is the lack of respect for teenage girls desires (it doesn't happen with teenage boys, see shonen manga).

Again, I haven't read it, but I don't think she is arguing that Bella being portrayed as a sexual being but not a sexual object and instead making Edward the sexual object (and touching lots of teenage girls Ids) overcomes, or even makes less important, the uber-problematic aspects of the books.
