Why does this conversation always have to exclusively revolve around how young girls treat each other? Young boys are awful to young girls. Women and men are awful to young girls. The question you should be asking is why do we as a society tolerate people (of any age and any gender!) being so awful to girls?
The article is about Facebook, the company. Facebook isn’t run by young girls. And yet many comments in this thread are focused not on Facebook’s responsibility to (and profiteering from the exploitation of) girls mental health and are instead focused on blaming the girls themselves.
Seems more than a little backwards to me.
