Hmm I actually agree with some of her points...
I think there is this perception that we are "imposing" sexuality on girls when it is far, far more complicated than that.
For a start, young girls are probably very sexual already - see that thread recently where women admitted having orgasms as early as six.
I think the campaign confuses 1. a terror of paedophiles and 2. a terror of the culture that young women are growing up in. I don't think it really deals with either very well.
The problem really is that adult women are sexualised. Girls aspire to be like adult women. I think we are trying to intervene into that, but it's pointless. We could say 1. We are campaigning against adult women being sexual objects (cf. the objective of the organisation Object) or 2. We are giving young girls alternate role models (cf. the objective of the Pink Stinks campaign). As it is, we are trying to prevent girls from aspiring to be like adult women, when that's what they do. And also saying that there is something wrong with young girls experimenting with being sexual in the way that adults are - which again, is what they do.
It's very complicated to articulate but I think that's the point she is trying to make, and I have some sympathy with her position.
