Following the 2016 Grammy Awards, Amy Schumer posted an Instagram photo with the caption "Taylor that's not a thigh gap. This is a thing gap." Schumer was referring to Taylor Swift, who showed up to the Grammy's in a dress that clearly accentuated her legs.

Amy Schumer has been known to use her platform, her comedy, to talk about body image. She has numerous quotes about loving the skin you're in, and not accepting standards put out by the media as universal, which is wonderful. Everyone should be empowered, and should feel beautiful and good enough, whatever they look like.

However, Schumer's Instagram post is representative of a problem -- a mistake that people often make when trying to empower. She tries to support one group of people, while tearing another down.

While her intention may have been to support and connect with women who do not have thigh gaps, she ultimately criticized and degraded another group of women: those who do have thigh gaps.

This kind of backwards empowerment is not uncommon, especially in terms of body image.

For example, take a look at Meghan Trainer's "All About That Bass." This seemingly empowering song loses some of its credibility when you dissect its lyrics. While "every inch of you is perfect from the bottom to the top" is a wonderful lyric, there are also lyrics like "skinny bitches" and "boys like a little more booty to hold at night." While it's subtle, there is a undertone of skinny shaming within this song. The song rightfully empowers curvy women, but it implies that skinny women are less desirable to men, and are just bitches, who think they're fat.

(Here's a parody of this song that makes it much more empowering.)

This is a problem. When you empower one group by tearing another down, there is no progress.

So how can we make this progress? Well, perhaps we need to take a look at some movements who are doing things right.

The Black Lives Matter movement (despite what some may be saying) has mastered the art of building people up without tearing others down. Black lives matter simply reminds us, in a time when it appears that some may be forgetting, that black lives do matter. It does not, in any way, claim that non-black lives don't matter.

And there's the difference. Both Schumer and Trainer have sent a message that "Curvy women matter, but skinny women do not." Black Lives Matter has simply sent the message that black lives matter. Period.

This is what we need. More campaigns like these, which remind us of the importance and value of an underprivileged or under-recognized group, without feeling the need to simultaneously devalue another group.

Because that's what we're all aiming for: equality. All body sizes should be valued. All people should be valued, regardless of race or gender. Movements start in order to raise up the group that has been pushed down. Movements fall apart when they instead try to push down those who are already on top. Build up, don't break down.

Thank you, Black Lives Matter, for setting an example of true empowerment.
