Plus-size fashion and body positivity vlogger Corissa Enneking, aka "Fat Girl Flow," caused a firestorm with her latest YouTube video.

This is the spark that caused the blaze: "Do not look me in the eye, tell me you are on Weight Watchers, and then in the next breath, tell me that you are body positive," she said forcefully.

The video — titled "Dear body positive YouTubers: That's not body positivity" — is addressed to her contemporaries in the blogosphere, but it's her fans and commenters who took offense. 

From viewers with constructive criticism to one person who just said, "This video is complete shit," many felt personally attacked, discredited, and excluded by her definition of who is and isn't body positive. 

Enneking says she made the video because she feels like the body positive community has been "a little bit stagnant lately." She draws a line in the sand between fashion bloggers and activists, saying, "There's a big difference between liking plus-size clothing and being fat and actually being body positive." 

She says plus-size bloggers who "don't care about body positivity" should take a back seat. 

No specific bloggers who "promote shit that's not body positive," as Enneking described, were called out in the video. 

Days after the video posted, she stood by her position that you can't be on a diet and be body positive.

This "point system" reference is another slap at Weight Watchers users.

And this tweet went out a few days before she posted a follow-up video to address the negative comments and clarify her thoughts.

Her response video — titled "Is dieting body positive?" — puts a target on diet culture, but doesn't really address whether people who follow diets like Weight Watchers can be body positive, by her definition.

What the video does do is shed light on why Enneking is so passionate about this topic. 

She developed an eating disorder at age 9 and, because she didn't physically look like she had an eating disorder, doctors told her and her family that her weight loss was perfectly healthy. 

This is an immensely important topic that's deserving of more attention, and her experience is heartbreaking to hear. 

Ironically, though, Enneking's stance on dieting has put her in the same boat as the bloggers who prompted her rant.

She's upset that fashion bloggers and the like are diluting body positivity by defining it in broad strokes and participating in diet programs. 

But even more dilutive to the body positive movement is the idea that it's some kind of exclusive club with strict rules. 

That's just not very welcoming. 

And it's not a sentiment that will bring more of the mainstream into the movement, which has exploded, but still has a long way to go.
