I'm a huge fan of "If you don't like something, don't do it." That includes all sorts of things, reading, sex, birth control, etc.
We still have this strange double standard regarding sex in America. First, we allow more violence than sex to be portrayed in media, AND it's more ok for males to have a sexual drive than it is for females.
Women, whether we like to admit it or not are still subconsciously viewed as property. I honestly did not realize how much so until this year's birth control controversies took so much media time.
This particular series I have not read, because I am a word snob and too much internet lingo drives me bonkers. However, I can see that it could be empowering for girls who are going through that stage of life and need to know they are perfectly within the realm of 'normal'. Also, this world is not the one I grew up in. I don't see kids saying 'gnarly', 'totally rad', or 'like a mug', which irritated the crap out of my grandmother. It's only fitting they'd have something that irritates the crap out of me with the text chat. ;)
