If that's why you won't run this blog anymore then why don't you turn it into something positive for women? Like a feminist confession blog. Encourage positive confessions, give out information about modelling, talk about valuable changes in the industry, etc. It doesn't always have to be all about bad gossip.
Because fashion enforces capitalism and the beauty industry, toxic ideals of what it means to be a "woman" and views women as objects. Because fashion exults six-inch heels to emphasise the sexual organs and tight dresses that serve to mark women out as other, to distinguish them from men - who don't fall prey to the venom of advertising and cultural condition nearly as much. Because it's poisonous for so many people. Because the modelling industry targets vulnerable young women and dumps them at the drop of a hat. Because fashion is inherently exploitative and capitalist, and I don't want to waste my time with it any more. I don't push for reform within a destructive, oppressive system. It makes no sense for me to define myself as a political radical yet still participate in the upholding and glorifying of this industry and the demeaning of women and girls based on a subjective opinion of how "good" they are at an arbitrary job.
I'm done with it. My interest in it won't go, of course. I love the dreams fashion can conjure up. I don't like its reality.
