This week, an Australian site caught viral fire when it released a breast self-exam video designed to pass the rigorous censors at Facebook — which, apparently, shield all of us from the potentially damaging sight of female breasts being portrayed as something other than something to wolf-whistle at.

In conjunction with the Argentine cancer support group MACMA, the Aussie site pulled off this feat by swapping in a nice pair of doughy, hairy man boobs being prodded from behind by the hands of the woman who, in any semblance of a sane world, would have been allowed to just do this herself.

In doing so, they illuminated a longstanding and laughable double standard when it comes to female nudity on social media. Last year, Facebook found itself on the defensive when it banned a photo of a woman breast-feeding — then clarified that their policy DOES allow breast-feeding photos, just not ones that show nipples (in case you failed Anatomy 101, that’s where the breast-feeding takes place).

Never mind that trumped-up nipple-terror is so rampant in real life it results in things like this week’s story about Brooklyn Decker being abandoned at an airport after having to slink off a plane to pump breast milk in a restroom (“Do you pump in your seat on the flight?? Or the bathroom?? #Spiraling,” she tweeted at the time).

Or, earlier this month, a woman being illegally ordered out of a courtroom for breast-feeding during her custody case: “Ma’am, you need to cover up. That’s . . . for you not to realize that is absolutely ridiculous,” said the judge. “Step outside and cover up right now. Stand up and go.”

On social media, the nipple has become the Rubicon — heaven forfend, anything but the nipple! This, of course, means a wide range of demeaning, sexist and exploitative photos and videos of women are just fine. It’s too risqué for a woman to post a photo of herself breast-feeding or doing a breast exam — but as long as you don’t show nip, it’s A-OK to post any wildly objectifying photo or video of near-naked women.

But hey — if man boob passes muster on social media, perhaps women should simply start Photoshopping them onto breast-feeding videos. Onto partial-mastectomy photos. Onto any media, really, that depicts women’s breasts as nonsexual entities. Really, Frankenstein up every photo that remotely depicts women’s bodies in a natural, nonsexualized way.

Let’s demand a little tit for tat, though: For every man boob swapped in for a scary female one in real-world photos and video, we’ll do likewise in “Game of Thrones,” which has arguably made its name on the bared female form. Would a month or two of topless Hodor have social media police singing a different tune?
