The newest issue of HipMama magazine features a photograph of artist Ana Alvarez-Errecald standing, topless, holding her baby. He's wearing a Spiderman costume and she is wearing the mask. The child is breastfeeding at one of her breasts and holding his hand over the other. After distributors expressed concern about having the magazine on US newsstands, HipMama was forced to publish not one, but two, covers: a "family-friendly" one that ensured it would be sold on newsstands and in supermarkets in which her bared breast is hidden by a large red dot and another, mailed to subscribers, in which her child's hand on her breast will be apparent. Alvarez-Errecald's most prominent earlier work, a diptych titled "The Birth of My Daughter," is also being published in the magazine. Trust me, that piece will not be appearing on magazine covers anytime soon.

The cover image has been removed on Facebook as obscene and the artists' Facebook page was, erroneously or not, unpublished. It cataloged her work, which included other images of bare breasts and had more than 2,000 followers, now lost to her.

In the wake of last year's #FBrape campaign, I have been in regular touch with Facebook on the topic of "the nipple problem." People often contact me to ask for help when Facebook moderators, sometimes misinterpreting their own guidelines, remove content in which nipples aren't even apparent, but where content related to reproductive health, pregnancy, labor, childbirth or, as in this case, breastfeeding are removed. In each instance, Facebook, which is grappling with these issues every day, has sought to rectify the problem as quickly as possible. Nipples, however, remain taboo with ass-backwards, sexist results like this: Nude and Naked Desi Girls, which has no breasts-not-in-the-service-of-the-male-gaze scary nipples, makes the obscenity cut.

While a lot of attention is paid to Facebook's oddly puerile, fundamentalist belt approach, I know from working with them that they are putting a lot of time and effort into understanding these ideas and addressing content removal biases. However, the company, a virtual country of 1 billion people, really just reflects mainstream US values the way that the Motion Picture Association of America, the Parents Television Council and the Federal Communications Commission do. For example, the PTC loudly criticized Miley Cyrus' "lewd" MTV Awards performance for its sexual explicitness, but didn't have a word regarding the rape apology of her co-performer's "Blurred Lines" song or either of their appropriations of African American music and culture. Their norms incorporate discriminatory standards every day. They are not interested in women's autonomy or freedom of speech.

These agencies, and social media company policies, like many city statutes and public ordinances, privilege male-dominant heterosexuality, conflate women's bodies with indecency and sex (a bad thing compared, for example, to allowable rampant violence), and insist that those bodies (and sex) be held in reserve, distributed and consumed according to patriarchal rules. These rules, and the obsessions that drive them, promote billion-dollar "good girls gone wild" industries and an Internet fueled by gonzo porn, which have little to do with women's autonomy.

Many people, seem confounded by expressions of female nudity that are not sexual -- because, of course, isn't male titillation the whole point of women's nakedness?

Why is exposing the world to non-sexualized female nudity important? The real question about female nudity isn't why anyone would want to show or see women's breasts if they're not titillating. The real question is about who has the right to say what they're for, where and when they can be seen and by whom. That's about power.

1. Women too often are used to embody and reflect male power, honor and shame. It's not good for us. Our bodies, and the bodies of people who are gender fluid and non-binary conforming, are sites of moral judgment in ways most men's are not, especially in public and in protest. Some of us experience our bodies, in particular our nudity, as objects of repression, oppression and powerlessness. Representing them as no one's but our own, counter to prevailing representations, is important.

2. Female public nudity is usually treated as a moral offense, a cause for concern and discussion, but it's rarely allowed to be a source of non-sexual female power. Male nudity is an entirely different thing. When your average (straight) man is seen nude or semi-nude, it's often considered humorous, as in frat boys streaking. Or it's a sign of virility and athleticism. When it's not, for example, the jarring images of the torture of Iraqi men in Abu Ghraib, men -- vulnerable, humiliated and in pain -- are feminized by their nakedness.

3. Female nudity is not just about sexualization, it's about maintaining social hierarchies, like those of race and class. Non-idealized female bodies used autonomously undermine a continuous narrative about body-based sex and race differences. When our cultural production is singularly focused on hyper-gendered, racialized and sexualized representations of nudity, it is easier to maintain racist and sexist ideas -- and nude female bodies outside socially approved, sexualized contexts challenge those.

The cultural regulation of female nudity and portrayals of sexuality is also a powerful way in which women's bodies are used to pit us against one another and to reinforce hierarchies among men. Dark bodies, especially women's, have always been available for public consumption: sale, rape, breeding, medical experimentation and more and the staying power of racist and sexist mythologies about white women and black men, rape and sex, are evident every day. When women take ownership of the circumstances of their own nudity, they can defy others' attempts to place them within these hierarchies.

5. It's not just that women have the right not to be sex objects, but also that we have the right to dismantle a discriminatory canon. In her 1977 essay "What's Wrong With Images of Women?" art historian Griselda Pollock described a global, commercial, patriarchal visual culture that uses women's bodies symbolically and makes it impossible for us to use our own bodies effectively in challenging that culture. It's a symptom of women's position in the world that the efficacy of using our nudity to protest is tenuous. Again, take Femen. Set aside their execution and bizarre provenance and focus on two things: a) their use of naked female bodies to express aggression and rage, and b) the fact that they appear to meet the requirements of Western, increasingly global, ideals of beauty. They are thin, young, tall, topless and almost all white. In Louise Pennington's words, they pass the patriarchal fuckability test. And so media eat them up. The same media that every day make choices about what not to show: models protesting racism in their industry; angry, anti-Catholic feminist crowds; peaceful, determined, old Nigerian women. That's not Femen's fault. They certainly aren't the ones making media decisions about what makes the news. Did they use this bias? Should women? Femen is exactly why many feminists doubt that female nudity can ever be an effective tool of activism. However, each controversy that erupts allows us to think about how our own bodies and their "place" are used to undermine our intent and desires.

6. Self-defined public female nudity is a challenge to capitalism and its uses of women as products, props, assets and distributable resources. Nothing on Earth is used to drive sales and profits and display male wealth and status like women's, often naked and semi-naked, bodies. If you are thinking women make choices and are complicit, show contempt for other women because they are women -- well, of course some of them do. That is a defining feature of misogyny. Until we have equal access to resources, and are not subject to constant predation, this is a no-brainer. In the meantime, when women refuse to sexualize themselves and use their bodies to challenge powerful interests that profit from that sexualization, the words we should use aren't "lewd" and "obscene"; they're "threatening" and "destabilizing."

I was alerted to Alvarez Errecald by Laura Dodsworth, a photographer and founder of an art and social project called bare reality. Like the documentary Free the Nipple and other movements addressing control of women's bodies and expression, this project is dedicated to positively altering the relationship between how women experience life and media depictions of the same. It's easy to trivialize their efforts, but that would be a serious mistake.

We all know that the prohibitions on women's nipples have nothing to do with women's nipples, but everything to do with control. Women who use public nudity for social commentary, art and protest are myth-busting along many dimensions: active, not passive; strong not vulnerable; together, not isolated; public, not private; and, usually, angry, not alluring. The threat that female toplessness and self-articulated nudity poses is culturally defined and can be culturally redefined so that people recognize that the offense to morality is misogyny, not nudity.
