Bieber's butt pic soon accumulated two million likes, and of the 600,000-plus comments, a vast majority are from fans expressing their love and/or excitement for the singer's naked body.
When women do the same thing, they're often called names or even censored by the media platform itself (as Chelsea Handler famously was multiple times after posting photographs where her nipples showed).
To highlight this disparity, Tumblr user moanhowell took a screenshot of the comments on Bieber's post and compared it with comments on a photo recently posted by Demi Lovato where she's wearing a bikini top and what appear to be board shorts.
The differences in responses to the two photos are troubling, to say the least. While Bieber was praised and glorified for his pic, Lovato was called "slutty" and "degrading."
Moanhowell also showed how Bryana Holly was shamed for posting this photo of herself on Instagram.
The posts inspired others to share similar examples of double standards in the media, citing both actual events and hypothetical situations.
While we already know women in the media are held to impossible standards, seeing how violently the responses to male and female nudity clash is more than a little jarring.
Fortunately, ladies know how to take a stand...
...and the growing interest in gender equality and women's rights issues means our voices will only continue to get louder.
