I'm very opposed to Facebook and social media in general. I think social media is bad for almost everybody. (and certainly bad on the whole for any large cohort.) Even if teenage girls were not predisposed to this sort of behavior, Facebook would still be bad for them. It would simply be bad for them in the ways which it is bad for everyone else. Instead, it's bad for them in all the other ways it's bad for people, and additionally bad for them when it comes to these particular social behaviors.
