When it comes to the question of whether punishing kids physically is acceptable, opinions vary widely — and people on both sides of the issue are passionate about their stances, though only one is supported by research. Over the weekend, a viral Facebook Live video of a mother assaulting her teenage daughter for several minutes reignited that debate. Here's everything you need to know about the Nia Green video, because the upsetting footage raises important moral and legal challenges about raising children and disciplining them in the era of instant communication.

A video of a woman The Root identified as Shanavia Miller beating her 16-year-old daughter with both a piece of plywood and her bare hands is racking up views all on the internet — and, unlike many viral videos of violence, that's no accident on the perpetrator's part. Seeing a Facebook photo her daughter, Nia Green, posted of herself posing in a towel with a boy was the reported catalyst the physical altercation. An unidentified person who does not appear in the video streamed the interaction live on Facebook, as Miller punches and slaps her sobbing daughter in the legs, stomach, face, and elsewhere. (Here is the graphic video, which may be triggering for victims of violence and assault.)

Romper reached out to Miller for comment and will update this post if and when she responds.

Throughout the video, Miller screams at her daughter, calling her a thot (an acronym that stands for "that hoe over there") while hitting and punching her over and over and over again as the teenager cowers and cries. Still, some internet users are supportive of Miller's actions:

At the end of the video, Miller takes hold of the camera and shoves it in Green's face as the girls attempts to hide behind her hands. Remember, this is all streaming live on Facebook.

Then Miller turns the camera on herself and fixes her hair, declaring that she'll take over Green's Facebook page from now on. "Now, I'm gonna need you all to send this viral," she says. "Please share this, cause I'm not done. More to come."

Then, from her daughter's account, she posted a message to those who watched the video:

I love my daughter with all my heart what ever happens after this o well my daughter is not going to disrespect me or herselffor nobody that shit Bernie Mac !!! Ain't nothing change she still my baby girl 💯💪 lesson learned now have a blessed day

And on Sunday evening, a post appeared, and its writer claimed to be Green herself:

First Off I Shouldnt Embarrassed My Moma , I Love Her . Yes this is me . Niaaa . I Shouldnt even been doing what i did. No i didnt have vari in my house when she said not to . I was at his house . Im only 16 yrs old . I was gonna open up and tell her that i was having sex . I was just gonna wait a couple days to see how i was gone tell her . I understand why she did what she did . Everybody laughing and making reenactments . Sharing my pictures im seeing everything. I did go to the hospital only because i have exotic attacks & real bad head ache . I embarrassed my moma so she embarrassed me . Im not defending the live video cas when school start next week all eyes on me . Im at work all eyes on me . I kno next time to just keep my business to myself

Many of the reactions to the video focused on the fact that this was a situation between a mother and her child. What would they think, though, if it were a stranger beating a teenage girl that way? Or a classmate, or even a father or other male guardian?

Study after study has shown that spanking is most definitely bad for kids, and the punishment depicted very clearly in the Nia Green video goes well beyond an open-handed slap to the behind. Regardless, the only objections some Twitter users had to it was that it made it onto the internet — not that it happened:

It's unclear if Shanavia Miller will face legal charges. But the legality of such an instance is far from the only reason that this never, ever should never happen or be seen as an acceptable form of punishment.
