Pretty much every feminist is interested in how women are depicted in media and film, Toby. Given that you know so much about the subject, I'm sure you're aware of why. All those silly little things about aspiration and psychology.
I'm not sure anyone is suggesting that women can't be photographed with their breasts out, however, when 'women looking attractive' is the only narrative about them, then we have a problem. Having the only depictions of women in certain types of newspaper as passive and decorative reinforces the idea that that is all women are good for. If men see women solely as passive and decorative, why would they need to consider their feelings or even bodily autonomy?
The way women are viewed is central to feminism. It shapes women's lives.
No doubt you'll now just tell me I'm stupid or don't know what I'm talking about, or make some puerile comment. I might try and care. I probably won't though, your opinions about women are clear.
