I normally would have posted this in the Parenting News forum, but I think it's more appropriate here, in the Preteens and Teens forum.
I've had my rebellious moments as a teenager girl, and I think it's normal for every young girl to go through that phase. However, what I'm seeing in pop culture these days is quite disturbing. I cannot image how it must be to a mom of a teenage daughter today and have to witness all the sexualization and self-objectification of teenage pop stars that young girls take on as role models.
Reading Sinead O'Connor's open letter to Miley Cyrus today was a breath of fresh air. I am not a feminist either, but her letter is really spot on. Someone had to come up and say it. And I'm glad and grateful Sinead stepped up and did.
Quote from the letter:
"Nothing but harm will come in the long run, from allowing yourself to be exploited, and it is absolutely NOT in ANY way an empowerment of yourself or any other young women, for you to send across the message that you are to be valued (even by you) more for your sexual appeal than your obvious talent. [...] Whether we like it or not, us females in the industry are role models and as such we have to be extremely careful what messages we send to other women. [...] I’ve been in the business long enough to know that men are making more money than you are from you getting naked. Its really not at all cool. And its sending dangerous signals to other young women."
